Feature/android node networking POC integration

[rodvar]

• Implementation for https://github.com/bisq-network/bisq-mobile/issues/6
• with this PR the androidNode app is in a state where it shows on screen anything that has been developed in shared adding the below:
  • connects to bisq2 network
  • creates a profile if not created and persisted already
  • observes and logs network information
  • listens for private messaging (this is gonna be our trading mechanism!)
  • listens for public messaging (for chat / not included in the MVP but nice to have)
• to not over complicate things its left like this for further development on architecture that's coming to happen.
