This adds some text to the documentation about configuring the import
mechanism, including details about shared vs. local staging
directories. It also clarifies that *all* import methods require the
staging directory to be configured, as well as cleans up some
single-store-specific wording in this area.

Newly added multiple import fails if user passes "all_stores" as "true"
in the request. The reason is if all_stores is specified then we are getting
stores using CONF.enabled_backends and unfortunately we are injecting
reserved stores 'os_glance_staging_store' and 'os_glance_tasks_store'
runtime. As a result import job tries to import the image in the
'os_glance_staging_store' store as well where it fails as that image
is already staged in this staging store.
Made a provision to exclude available reserved stores if "all_stores"
is specified.

Closes-Bug: #1863879
In Rocky multiple backend support is added as experimental feature. In
order to take advantage of this feature it is decided to deprecate
work_dir and node_staging_uri configuration options
and reserve two filesystem stores 'os_glance_tasks_store' and
'os_glance_staging_store', which can be used to get rid of initializing
store via internal functions.
These internal stores are considered "reserved stores" by Glance.
For the time being, these are hard-coded as filesystem stores. The
store prefix 'os_glance_' is reserved for internal Glance use and
the glance-api service will refuse to start if a store with this
prefix is included in the enabled_backends config option in
glance-api.conf.
NOTE: Because there are no sensible default values for the location
of the datadir for each of these stores, the operator must define
'os_glance_tasks_store' and 'os_glance_staging_store' in
glance-api.conf configuration file as shown below.
[os_glance_tasks_store]
filesystem_store_datadir = /var/lib/glance/tasks_work_dir/
[os_glance_staging_store]
filesystem_store_datadir = /var/lib/glance/staging/
Each filesystem store must have a unique datadir.

Made changes to discovery store to show 'http'
store as 'read-only' if it is configured under
'enabled_backends' cofiguration option.
