Using JWT and proxy connection

[countnazgul]

JWT authentication method is working ok in both cases - connecting directly to the engine (port 4747) and via the virtual proxy.

The issue is that every time when establishing connecting through the VP new session is created. This quite quickly can reach the max concurrent session limits (5) and block the JWT user from connecting (until the sessions are timed out).

The JWT connection logic should check if the connection should be established through VP or not and if yes then:

• try to connect with session id (if session file exists)
• first make request to the hub (via VP) and extract the sessionId
  • use the sessionId to establish connection
