Clients can be deleted by owners and admins

[christad92]

As a client owner or admin I should be able to delete an oauth client. Before deleting, the user must confirm they want to proceed to delete through a modal.

Expected Behaviour: The oauth_client_id of the credential will be set to NULL.

Associated credentials might work until there is a need for a refresh of the token and would require the user to remove and the credential and and set up a new credential.
