[RFE] Add support for Access Metadata

[Goutham Pacha Ravi]

API version 2.45 was added in OpenStack Rocky and it introduced new API functionality to:

- retrieve/add/update access rule metadata (https://docs.openstack.org/api-ref/shared-file-system/#share-access-rule-metadata-since-api-v2-45)
- new endpoint to list access rules (https://docs.openstack.org/api-ref/shared-file-system/#share-access-rules-since-api-v2-45)

Hello, I am an outreachy applicant this year. Will this issue be okay to start with?
