Amend spec for add-instance-name-to-cli

I noticed that the RST formatting in the spec wasn't correct.
This attempts to correct those issues.

-user-list
-user-revoke-access
-user-show
-user-show-access
-user-update-attributes
+Allow instance-id or instance-name to be passed in for the following commands:
 
-For example, trove delete currently looks like this:
-usage: trove delete <instance>
+- backup-create
+- backup-list-instance
+- configuration-attach
+- configuration-default
+- configuration-detach
+- database-create
+- database-delete
+- database-list
+- detach-replica
+- delete
+- metadata-create
+- metadata-delete
+- metadata-edit
+- metadata-list
+- metadata-show
+- metadata-update
+- resize-flavor
+- resize-instance
+- resize-volume
+- restart
+- root-enable
+- root-show
+- update
+- user-create
+- user-delete
+- user-grant-access
+- user-list
+- user-revoke-access
+- user-show
+- user-show-access
+- user-update-attributes
 
-Deletes an instance.
+For example, ``trove delete`` currently looks like this:
 
-Positional arguments:
-  <instance>  ID of the instance.
+::
+
+    usage: trove delete <instance>
+
+    Deletes an instance.
+
+    Positional arguments:
+        <instance>  ID of the instance.
 
 The proposal is to make it look like this:
-usage: trove delete <instance>
 
-Deletes an instance.
+::
 
-Positional arguments:
-  <instance>  ID or name of the instance.
+    usage: trove delete <instance>
 
+    Deletes an instance.
+
+    Positional arguments:
+        <instance>  ID or name of the instance.
 
 This will be a CLI change only.
 
+Currently the ``trove show`` command will display an error if there is
+more than one instance with the name provided. The error indicates that,
+in this case, the instance ID must be used. This behavior will be preserved
+and used across all the commands mentioned above.
