The livereloading script from ibazel is currently served at a non-static URL. Meaning
that we can't just add a script import to the livereload script in the index.html.
If the ts_devserver uses the concatjs bundle it works because the devserver go
implementation currently reads the IBAZEL_LIVERELOAD_URL environment variable
and adds the script to the concatjs bundle automatically.
In the other scenario where concatjs is not used, developers need a way to specify
where the livereload script should be loaded from (meaning that there is a predictable
URL for the script). This commit adds a flag to the devserver binary that can be used to
set a specific URL where the livereloading script should be served from. This is achieved
by forwarding all request for that URL to the actual ibazel livereloading script.
