HDFS-16887 Log start and end of phase/step in startup progress

[virajjasani]

As part of Namenode startup progress, we have multiple phases and steps within phase that are instantiated. While the startup progress view can be instantiated with the current view of phase/step, having at least DEBUG logs for startup progress would be helpful to identify when a particular step for LOADING_FSIMAGE/SAVING_CHECKPOINT/LOADING_EDITS was started and ended.

+1, pending CI.

Thank you, @virajjasani !
