There is a typo in the endpoint group deletion, due to this you
can't remove endpoint groups once assigned. I am adding also the
unit tests to avoid this kind of issues in the future

(cherry picked from commit 04e03b2a1fe34046e2148d3c1d17b9053010c8af)

Regsitered limit set CLI takes --service, --region and
--resource-name as param which can be updated along with
--default limit for existing registered limit.

Default limit can be updated with same value and CLI
return the success. But --service, --region and --resource-
name cannot be same as existing one. CLI return 409
for this case. Which is valid behaviour because more than
one limit with same service and same resource cannot exist.

But help message of --service, --region and --resource-name
are not much clear to tell that they cannot be passed with
same value.

This patch clarifies the help message for resigtered limit set CLI.

Reference Scenario:
*  openstack registered limit set --default-limit 91 64c2e97fbe904b888544ffdcab21989b
limit updated sucessfully

Updating limit with exsiting service and resource-name:

* openstack registered limit set --default-limit 92 --resource-name snapshot 64c2e97fbe904b888544ffdcab21989b
Conflict occurred attempting to store registered_limit - Duplicate entry. (HTTP 409)

*openstack registered limit set --default-limit 93 --service compute 64c2e97fbe904b888544ffdcab21989b
Conflict occurred attempting to store registered_limit - Duplicate entry. (HTTP 409)

*openstack registered limit set --default-limit 91 --resource-name snapshot --service glance 64c2e97fbe904b888544ffdcab21989b
Conflict occurred attempting to store registered_limit - Duplicate entry. (HTTP 409)

When user passes --region None, the find_resource
of osc_lib calls get() of region. The get API of
region ignores the name param returning all the
regions in result. As the find_resource checks
many cases against the result returned by get API.
The output comes greater than 1, thus returning
"More than one region ID exist" which is incorrect.
However in case of region which cannot be filtered
by name we do not require to check these many cases.

The solution is to directly call the get method of
APIs and returning No resource name exist with the
xyz" on passing invaid parameter. And returning all
in case of None.

Thus created a new function get_resource which can
be used in future too by these types of API's.

when doing openstack limit list --project xyz_id,
CLI raising error unrecognized arguments, whereas
in api-ref document [1], user can pass project_id
as query param.This addresses the above issue, by
adding param --project in parser of LimitList.

Closes-Bug: #1798744

The --project and --project-domain flags are currently mutually
exclusive for listing endpoints, however the --project-domain argument
is supposed to help with filtering projects with colliding names. They
should be allowed together.

The code was calling an unexisting function which never existed.
The module refers now to the correct `InferenceRuleManager`. It
also allows the compatibility with the future python-keystoneclient
in which the compatibility method will be removed from the
RoleManager.
