Validation for List servers by server name - expected error responses not returned

[Rohit Karajgi]

Our tempest tests run the following validation test for List Servers "by server name" API and fail
as the expected error codes are not returned.

1. test_list_servers_by_server_name_empty - Return an error when an empty server name is passed

Expected Error Code - 400 BadRequest
Actual Code - 200 OK

2. test_list_servers_by_server_name_too_large - Return an error for a very large value for server name listing

Expected Error Code - 413 Overlimit
Actual Code - 200 OK

3. test_list_servers_by_name_pass_numeric_name - Return an error for a numeric server name listing

Expected Error Code - 400 BadRequest
Actual Code - 200 OK

4. test_list_servers_by_non_existing_server_name - Return an error while listing for a non existent server

Expected Error Code - 404 NotFound
Actual Code - 200 OK

The List Servers API for listing by name should send the Expected error responses as above

The return code of filtering a list should typically be 200. The only thing that should be changing is what is contained in the list returned to clients. Please only file bugs based on mis-implementation of the API spec, not your personal opinion.
