[FAB-1960] Add peer test template

https://jira.hyperledger.org/browse/FAB-1960

Just like the orderer and MSP, the peer needs to supply a template so
that the configtx/test can generate a valid genesis block for testing
purposes.

This change adds the peer template and adds a test which generates it.
