test_integration.host: Move transport-related functionality to a new module

This will make it possible to use a different mechanism for cases like
- Paramiko is not available
- Hosts without SSH servers (e.g. Windows)

Add BaseHost, Transport & Command base classes that define the interface
and common functionality, and Host, ParamikoTransport & SSHCommand with
specific details.

The {get,put}_file_contents methods are left on Host for convenience;
all other Transport methods must be now accessed through the transport.
