Remove the requirement of file system access to run GCS unit tests. Deconstruct
the input parameters to take the private key and email which can be specified on
the build system via environment variables.

when returning errors.

Swift returns an empty object list when trying to read a non-existing object path, treat it as a
PathNotFoundError when trying to list a non existing virtual directory.

Issue #1186 describes a condition where a null tags response is returned when
using the s3 driver. The issue seems to be related to a missing
PathNotFoundError in s3. This change adds a test for that to get an idea of the
lack of compliance across storage drivers. If the failures are manageable,
we'll add this test condition and fix the s3 driver.

The Delete method lists objects under the given path and tries to delete
all of them with a bulk delete request. If the path has no objects
underneath it, the body of this request will be empty, which causes
HTTP-level issues. Specifically, Go's HTTP client senses the empty
request buffer and doesn't include a Content-Length, which causes the
Swift server to fail the request.
This commit fixes the problem by avoiding sending empty bulk delete
requests. This is the correct thing to do anyway, since there's no
reason to request deletion of zero objects.

Errors thrown by storage drivers don't have the name of the driver, causing user
confusion about whether the error is coming from Docker or from a storage driver.
This change adds the storage driver name to each error message.
This required changing ErrUnsupportedDriver to a type, leading to code changes
whenever ErrUnsupportedDriver is used. The tests check whether the driver name
appears in the error message.

In the S3 storage driver there is currently an initial access permission check by listing the bucket. If this check fails, registry will panic and exit.
However, this check is broken in two ways. First of all it strips the final slash from the root directory path, meaning that any access permissions which limit access to a single directory will fail, because S3 treats the path as strict prefix match. Secondly it fails to strip any leading slash that might be present, unlike the other access places, which means that the path used is different as a leading slash is allowed and significant in a filename in S3.
Since there is also a periodic health check which correctly checks access permissions and shows the error more cleanly, the best solution seems to be to just remove this initial access check.

When using the RADOS driver, the hierarchy of the files is stored
in OMAPs, but the root OMAP was not created and a call to List("/")
was returning an error instead of returned the first level files
stored. This patches creates an OMAP for "/" and excludes the listed
directory from the list of files returned.
