Use common replication wait timeout of 5min
    
    Instead of multiple timeout values all over the code base, all
    replication waits now use a common timeout value from api.env of 5
    minutes. Waiting for HTTP/replica principal takes 90 to 120 seconds, so
    5 minutes seem like a sufficient value for slow setups.
