Hemanth Makkapati 3ff3debc14 Remove "Services which consume this" section
In the first few improvements to the help text of configuration
options, the section "Services which consume this" was included
to clearly indicate which services consume a particular
configuration option. However, this is redundant information as
all glance services have their configuration files. And, the very
fact that a configuration option appears in a certain file
indicates that the corresponding service potentially consumes it.

Hence, in this patch we drop the redundant section from the help text
of configuration options it appears in. The configuration options
that are impacted are:
* public_endpoint (glance/api/glare/versions.py)
* owner_is_tenant (glance/api/middleware/context.py)
* admin_role (glance/api/middleware/context.py)
* allow_anonymous_access (glance/api/middleware/context.py)
* max_request_id_length (glance/api/middleware/context.py)
* public_endpoint (glance/api/versions.py)
* image_cache_driver (glance/image_cache/__init__.py)
* image_cache_max_size (glance/image_cache/__init__.py)
* image_cache_stall_time (glance/image_cache/__init__.py)
* image_cache_dir (glance/image_cache/__init__.py)
* image_cache_sqlite_db (glance/image_cache/drivers/sqlite.py)
* admin_role (glance/scrubber.py)

Public url endpoint to use for Glance/Glare versions response.
This is the public url endpoint that will appear in the Glance/Glare
"versions" response. If no value is specified, the endpoint that is
displayed in the version's response is that of the host running the
API service. Change the endpoint to represent the proxy URL if the
API service is running behind a proxy. If the service is running
behind a load balancer, add the load balancer's URL for this value.
Possible values:
* None
* Proxy URL
* Load balancer URL
