Add raw api module to nomos-cli (#511)

* Add raw api module to nomos-cli

Add a separate module which contains all raw api calls and make
them reuse the same reqwest client for increased efficiency

* Use json instead of wire format in mempool add api

Uniform all http api to use json as the encoding
