Added a sleep for 30 seconds for master to become active, so that I can see
that progress page is showing correct information.

> Add an internal API to the master for tracking startup progress. Expose this
> information via JMX.
> Modify the master to bring the web UI up sooner. Will require tweaks to
> various views to prevent attempts to retrieve state before the master fully
> up (or else expect NPEs). Currently, before the master has fully initialized
> an attempt to use the web UI will return a 500 error code and display an
> error page.
> Finally, update the web UI to display startup progress, like HDFS-4249.
> Filing this for branch-1. Need to check what if anything is available or
> improved in branch-2 and master.
