LIVY-319. Unify the indent for all POM files

[ajbozarth]

LIVY-319

Updated pom files that used 4 space indent to use 2 space indent to match the remaining pom files.

Not sure why the diff on GitHub is so weird, the only changes are the indent levels.

Also I believe this update makes every xml file in Livy use 2 space indent now

LGTM, thanks for the fix.
