Please add a separate property for loginTimeout

Hi, I'm using hikariCP in productions. I am really appreciate for your efforts.

Recently, i experienced failing a pool initialization. the origin of the issue is from connection timeout.
In database high load, db connection was made by slow. I could increase hikari connectionTimeout but I do not want to increase wait time for pool.
Actually, i resolved this issue by setting a system property for driver specific connect timeout
ex) for oracle, -Doracle.net.CONNECT_TIMEOUT
But, for other databases, other properties should be used.

If hikariCP provide a separate property for loginTImeout, It will be convenient.

I know there is a method like com.zaxxer.hikari.HikariDataSource#setLoginTimeout. But it affect only in case that pool is already created.

Thank you!
