Keep Maintainer for keep-test

This is a configuration for a maintaienr bot running in keep-test cluster.
The maintainer is connected to Bitcoin testnet and runs two modules:
- spv
- walletCoordination

This instance is not running the bitcoin difficulty module as the
current keep-test contracts setup requires the maintainer for difficulty
to be connected to mainnet Bitcoin.
