[RFE] a "--wait" option for creating/deleting a share group

[Goutham Pacha Ravi]

Expected workflow:

1) Creating a share group

$ manila share-group-create --name share-group-1 --wait
<CLI waits on the share group to become available before providing group details>

2) Deleting a share group

$ manila share-group-delete share-group-1 --wait
<CLI waits on the share group to be deleted before returning to the prompt>

    Add --wait flag to the delete share group operation

    This patch set adds the --wait flag to the share group
    operation. This will make the CLI to wait for the
    operation to be completed before returning to the prompt.

    Updated test_share_delete to be test_share_delete_wait
    and included the waiter flag.

    Updated test_share_group_delete_force to test the
    correct calls.

    Also, updated test_share_group_update and test_share_group_show
    since they were randomnly failing depending on the test execution
    order. Mocks were being cleaned up and that was leading us to
    some errors. Created mocks for required resources within those
    tests to make it more stable.

    Partial-Bug: #1898318
