"warning is not a valid state name " on vcenter connection tests

[Mikesch-mp]

Expected Behavior

No matter if the state is in lowercase or uppercase reported by vcenters it should work.

Current Behavior

if vCener send state in lowercase (dont ask me why) the check fails with unkown state

[UNKNOWN] warning is not a valid state name

Possible Solution

add $state = strtoupper($state); to the function wantNumericState

    protected function wantNumericState($state)
    {
        $state = strtoupper($state);
        if (is_int($state) || ctype_digit($state)) {
            if (array_key_exists($state, $this->stateNameMap)) {
                return (int) $state;
            } else {
                throw new InvalidArgumentException(sprintf('%d is not a valid numeric state', $state));
            }
        } else {
            if (array_key_exists($state, $this->nameStateMap)) {
                return $this->nameStateMap[$state];
            } else {
                throw new InvalidArgumentException(sprintf('%s is not a valid state name', $state));
            }
        }
    }
