[IPA] MVP to manually test vpr --server mode

[w0lek]

The vpr contains server mode functionality, where the vpr acts as a server instance, waiting the client's requests.
In order to check that feature in work we actually requires the separate client application.

Proposed Behaviour

New MVP IPAClient to work in conjunction with vpr --server mode.

[w0lek]

The MVP application is ready as separate github repo.
