Change number of connection attempts in QuicClientBase::Connect

This removes its dependency on GetNumSentClientHellos. Though instead of
comparing the number of connection attempts to kMaxClientHellos, it could
probably just try twice - once for whatever initial version the client is
configured for, and a second time for a new version in response to version
negotiation.
