Thank you for the PR. It works, but architecturally, setting the CA chain in TlsTransport is quite weird, since TlsTransport by itself doesn't perform certificate verification. I think the CA chain should only be set in VerifiedTlsTransport, which would also be simpler as you wouldn't have to forward cacert all the way down to TlsTransport. What do you think?

Moreover, you need to free mCaCert in the destructor and constructor catch block. I'm just noticing now that the TlsTransport destructor is not implemented for MbedTLS... I'm pushing a fix. @Sean-Der if you use Websockets with MbedTLS somewhere, there must be a memory leak.
