Add RPC Target

[hax0kartik]

This is a rough draft right now because there are certain areas which need to be improved before merging:

• Initialization : Preferably, we should report to the user in case the btcd server has not been executed yet. +1 if we can launch the server ourselves.

• Code Cleanup : Minor Code cleanup is needed
