ws_client: fix handling timeouts by websocket client.

Browse Source 
tcp-transport component did not support wait forever. this update uses value of -1 to request this state.
websocket client uses timeouts in RTOS ticks. fixed recalculation to ms (including special value of -1) to use correctly tcp-transport component

Closes https://github.com/espressif/esp-idf/issues/4316
