[THRIFT-5752] Add TTransportFactoryInterface

[sveneld]

I'm offer to add TTransportFactoryInterface for having a possibility to use own implementation of TTransportFactory in TServer.

I have a problem when I'm tried to make a TSimpleServer for client who used a
TFramedTransport. Current realization of TTransportFactory does not give me a possibility to add a TFramedTransport as a decorator for use TTransport

• https://issues.apache.org/jira/browse/THRIFT-5752
• If a ticket exists: Does your pull request title follow the pattern "THRIFT-NNNN: describe my issue"?
• Did you squash your changes to a single commit? (not required, but preferred)
• Did you do your best to avoid breaking changes? If one was needed, did you label the Jira ticket with "Breaking-Change"?
• If your change does not involve any code, include [skip ci] anywhere in the commit message to free up build resources.

How would compatibility affected? Does that change break existing code? If so, can we prevent that?

Combability should not be affected. Class TTransportFactory used only for creation of TServer.
I am just added an Interface for it, and replace all places of usage from TTransportFactory to TTransportFactoryInterface.
It should work fine.
