[#486] innerring: Add option to disable only main chain notary support

For N3 Testnet RC2 release inner ring app supports three modes:
- notary enabled in all chains (default),
- notary disabled in all chains,
- notary enabled only in side chain.

All notary related functions are moved to notary.go
