Incorrect Default Property Value in failover-project Example

[ericputnam]

The mlDatabaseNamesAndReplicaCounts property in

https://github.com/rjrudin/ml-gradle/blob/master/examples/failover-project/gradle.properties

should be changed from
mlDatabaseNamesAndReplicaCounts = ["Security": 2, "Schemas": 1, "Meters": 1, "App-Services": 1]
to
mlDatabaseNamesAndReplicaCounts=Security,2,Schemas,1,Meters,1,App-Services,1
