Commit changes default values from "unlimited" to lower and more
realistic values. Modified settings are:
* `maxConnectionLifetime` - changed from unlimited to 1 hour because it seems
reasonable to periodically "refresh" connections and make sure they are
not affected by network infrastructure.
* `maxConnectionPoolSize` - changed from `Integer.MAX_VALUE` to 100 because
unlimited connection pool is dangerous and might result in excessive use
of resources and OOMs in the database, if connections there are
not limited.
* `connectionAcquisitionTimeout` - changed from unlimited to 60 seconds
to not cause infinite blocking.
