This PR starts tendermint node wihtin the engine. It also allows connecting multiple engine instances of tendermint nodes.

DONE ON THIS PR

• start tendermint node
• create simple service app that is lunch with tender mint
• allow to connect multiple tendermint nodes (running in diffrent engine instances)
• create mesg-tendermint network for multiple engine instances (+ clean up dev script a bit)
• add config.Tendermint.P2P.Seeds
• create test-user and validators and put them .tendermint directory

TEST

# start in dev command
$ ./dev
# copy p2p ID  
INFO[0000] P2P Node ID                                   ID=c8876c507d7980ac09031a40a7495b59d942dba8 file=/root/.tendermint/app/config/node_key.json module=p2p

# in seperate terminal

ISSUES

coping a peer id form terminal is not the best way to connect two nodes, any ideas on how can I solve this? I thought put /root/.tendermint/peer_id file and then from the other terminal just cut it.

Is this ready for review? I see there is the database in the source, the service application where we talked about having just the tendermint node for now so maybe there is still some cleanup to do

We need some app to start tendermint node, but I can remove the serviceapp from this PR if needed.

[antho1404]

yes please and also remove the DB state and I think it's best not to have this .tendermint directory but configure all that directly in the source code especially the genesis.
