This change adds first-class metadata support to the Azure Blob backend,
including headers, user metadata, tags, and modtime overrides, and wires
it through uploads and server-side copies.
There is a behavior change in that rclone will now set the "mtime"
custom metadata when doing server side copies to azure and the
`--metadata` argument is given.
- Map standard headers: cache-control, content-disposition, content-encoding,
content-language, content-type to corresponding x-ms-blob-* HTTP headers.
- Map user metadata: any non-reserved keys (excluding x-ms-*) are sent as
blob user metadata. Keys are normalized to lowercase for consistency.
- Support tags: parse `x-ms-tags` as a comma-separated list of key=value
pairs and apply them on uploads and copies.
- Support mtime override: accept `mtime` in metadata (RFC3339/RFC3339Nano)
to override the stored modtime persisted in user metadata.
Backblaze has updated its b2_authorize_account API endpoint, newly created
application keys are now "multi-bucket" keys, capable of being limited to
multiple buckets. These keys can only be used with the v4 endpoint, not v1 which
returns an HTTP 400.
This commit switches authorization to the v4 endpoint, and allowing such keys to
work with any of the allowed buckets.
With multi-bucket keys, missing restricted buckets can be non-fatal.
Supports listing root with multi-bucket API keys
Replace custom rem hugo shortcode template with HTML comment. HTML comments are now
allowed in Hugo without enabling unsafe HTML parsing.
Improve the text in the comment: Remove unnecessary quoting, and avoid impression that
make backenddocs has to be run and results committed, since we have a lint check which
will then report error because we want to prevent manual changes in autogenerated sections.
Disable the markdownlint rule line-length on the autogenerated marker line.
Make the autogenerated marker detection a bit more robust.
See #8942 for more details.
