Add counter.ink OTC contracts to Krievo to enable p2p trading of krievo org assets

[monsieurbulb]

We should allow members of krievo orgs / satellite chains to trade assets p2p in the manner of local bitcoins etc.

basically allow organic grass-roots trade to build before DEX etc.

Kreivo orgs can easily become p2p trading communities thanks to our payments infrastructure and integrated encrypted communications. The Vito team will bootstrap one such community but many more can be created. Also the Virto app can include in the future an automatic selection of trading provider when users desire to pay with fiat currencies.
