This patch implements --use-server-modtime for the Azureblob backend.
It does this by not reading the time from the metadata if the global
flag is set.
The updates the authentication to include
- Auth from the environment
1. Environment Variables
2. Managed Service Identity Credentials
3. Azure CLI credentials (as used by the az tool)
- Account and Shared Key
- SAS URL
- Service principal with client secret
- Service principal with certificate
- User with username and password
- Managed Service Identity Credentials
And rationalises the auth order.
After speed testing it was discovered that upload speed goes up pretty
much linearly with upload concurrency. This patch changes the default
from 4 to 16 which means that rclone will use 16 * 4M = 64M per
transfer which is OK even for low memory devices.
This adds a note that performance may be increased by increasing
upload concurrency.

Includes adding support for additional size input suffix Mi and MiB, treated equivalent to M.
Extends binary suffix output with letter i, e.g. Ki and Mi.
Centralizes creation of bit/byte unit strings.
Create a full loop of documentation for rclone about, backends overview
and individual backend pages.

Previously pull was requested, in part, under ref
https://github.com/rclone/rclone/pull/4801
Notes:
Introduce a tentative draft see-link format the end of sections to try
rather than lots of in-para links.
Update about.go incl link to list of backends not supporting about.
In list of backends not supporting about, include link to about command
reference.
I appreciate there may be decisions to make going forward about whether
command links should be code formatted, and using proper pretty url
links, but I have fudged that for now.
Update backend pages that do not support about with wording used
previously for ftp - it is in passive voice but I can live with it. (my
own wording and fault). The note is applied to a limitations section. If
one does not already exist it is created (even if there are other
limitations with their own sections)
In 8a0775ce3c which was released in v1.49.0 we inadvertently
stopped SAS URLs working from the root without a container name.
Previously to this change you could use `rclone mount azsas:` and it
would actually be equivalent to `rclone mount azsas:container`. After
this change, only `rclone mount azsas:container` will work, `rclone
mount azsas:` will have a directory in the root called "container".
After some discussion it was decided not to revert this change as the
current behaviour is more logical and in line with the similar
behaviour for the b2 backend.
Instead the documentation was updated to show exactly how container
level SAS URLs behave.
Fixes#4028
* azureblob - Add support for Azure Storage Emulator to test things locally.
Testing - Verified changes by testing manually.
* docs: update azureblob docs to reflect support of storage emulator
