Kai Lüke 54f2587c1e gcs: add support for anonymous access 
Currently credentials are required to download a public bucket file
which is not really necessary and makes automated usage more complex.
Add a new option "anonymous" which when enabled configures the gcs
backend to use an anonymous HTTP client. This of course only works
for read access and trying to write will lead to errors like that:
"googleapi: Error 401: Anonymous caller does not not have
storage.objects.create access to the Google Cloud Storage object.",
as expected. By default the anonymous access option is disabled so that
the GCS Application Default Credentials are still used by default as
before and an error is given if they can't be found.

{{< icon "fab fa-google" >}} Google Cloud Storage
-------------------------------------------------
Paths are specified as `remote:bucket` (or `remote:` for the `lsd`
command.) You may put subdirectories in too, eg `remote:bucket/path/to/dir`.
The initial setup for google cloud storage involves getting a token from Google Cloud Storage
which you need to do in your browser. `rclone config` walks you
through it.
Here is an example of how to make a remote called `remote`. First run:
rclone config
This will guide you through an interactive setup process:
```
n) New remote
d) Delete remote
q) Quit config
e/n/d/q> n

Remote config
Use auto config?
* Say Y if not sure
* Say N if you are working on a remote or headless machine or Y didn't work
y) Yes
n) No
y/n> y
If your browser doesn't open automatically go to the following link: http://127.0.0.1:53682/auth
Log in and authorize rclone for access
Waiting for code...
Got code
--------------------
[remote]
type = google cloud storage
client_id =
client_secret =
token = {"AccessToken":"xxxx.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx","RefreshToken":"x/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx_xxxxxxxxx","Expiry":"2014-07-17T20:49:14.929208288+01:00","Extra":null}
project_number = 12345678
object_acl = private
bucket_acl = private
--------------------
y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y
```
Note that rclone runs a webserver on your local machine to collect the
token as returned from Google if you use auto config mode. This only
runs from the moment it opens your browser to the moment you get back
the verification code. This is on `http://127.0.0.1:53682/` and this
it may require you to unblock it temporarily if you are running a host
firewall, or use manual mode.
This remote is called `remote` and can now be used like this
See all the buckets in your project
rclone lsd remote:
Make a new bucket
rclone mkdir remote:bucket
List the contents of a bucket
rclone ls remote:bucket
Sync `/home/local/directory` to the remote bucket, deleting any excess
files in the bucket.
rclone sync -i /home/local/directory remote:bucket
### Service Account support ###
You can set up rclone with Google Cloud Storage in an unattended mode,
i.e. not tied to a specific end-user Google account. This is useful
when you want to synchronise files onto machines that don't have
actively logged-in users, for example build machines.
To get credentials for Google Cloud Platform
[IAM Service Accounts](https://cloud.google.com/iam/docs/service-accounts),
please head to the
[Service Account](https://console.cloud.google.com/permissions/serviceaccounts)
section of the Google Developer Console. Service Accounts behave just
like normal `User` permissions in
[Google Cloud Storage ACLs](https://cloud.google.com/storage/docs/access-control),
so you can limit their access (e.g. make them read only). After
creating an account, a JSON file containing the Service Account's
credentials will be downloaded onto your machines. These credentials
are what rclone will use for authentication.
To use a Service Account instead of OAuth2 token flow, enter the path
to your Service Account credentials at the `service_account_file`
prompt and rclone won't use the browser based authentication
flow. If you'd rather stuff the contents of the credentials file into
the rclone config file, you can set `service_account_credentials` with
the actual contents of the file instead, or set the equivalent
environment variable.
### Anonymous Access ###
For downloads of objects that permit public access you can configure rclone
to use anonymous access by setting `anonymous` to `true`.
With unauthorized access you can't write or create files but only read or list
those buckets and objects that have public read access.
### Application Default Credentials ###
If no other source of credentials is provided, rclone will fall back
to
[Application Default Credentials](https://cloud.google.com/video-intelligence/docs/common/auth#authenticating_with_application_default_credentials)
this is useful both when you already have configured authentication
for your developer account, or in production when running on a google
compute host. Note that if running in docker, you may need to run
additional commands on your google compute machine -
[see this page](https://cloud.google.com/container-registry/docs/advanced-authentication#gcloud_as_a_docker_credential_helper).
Note that in the case application default credentials are used, there
is no need to explicitly configure a project number.
### --fast-list ###
This remote supports `--fast-list` which allows you to use fewer
transactions in exchange for more memory. See the [rclone
docs](/docs/#fast-list) for more details.
### Custom upload headers ###
You can set custom upload headers with the `--header-upload`
flag. Google Cloud Storage supports the headers as described in the
[working with metadata documentation](https://cloud.google.com/storage/docs/gsutil/addlhelp/WorkingWithObjectMetadata)
- Cache-Control
- Content-Disposition
- Content-Encoding
- Content-Language
- Content-Type
- X-Goog-Meta-
Eg `--header-upload "Content-Type text/potato"`
Note that the last of these is for setting custom metadata in the form
`--header-upload "x-goog-meta-key: value"`
### Modified time ###
Google google cloud storage stores md5sums natively and rclone stores
modification times as metadata on the object, under the "mtime" key in
RFC3339 format accurate to 1ns.
#### Restricted filename characters
| Character | Value | Replacement |
| --------- |:-----:|:-----------:|
| NUL | 0x00 | ␀ |
| LF | 0x0A | ␊ |
| CR | 0x0D | ␍ |
| / | 0x2F | ／ |
Invalid UTF-8 bytes will also be [replaced](/overview/#invalid-utf8),
as they can't be used in JSON strings.
