Clients do not handle various views related errors

Views right now dont have logic to handle various views related errors like:-

1) Happens when user's query view immediately after its creation, (workaround was to wait and then try) :-
"reason": "Undefined set view `default` for `_design/dev_test_view_on_30000_docs-4f86b0d` design document."

2) This is expected, if we are trying to query views during topology changes. (workaround is to keep trying again)

{not_found,no_db_file},
n <<\\"Couldn\'t open database `default/208`, reason: {not_found,no_db_file}

\\">>}}}">>,\n <<"[

{couch_set_view,get_group_server,2}

,
n

There might be more related errors. Will update them here, if found.
