Juri Lelli 634c24068a tools/sched: Add dl_bw_dump.py for printing bandwidth accounting info
dl_rq bandwidth accounting information is crucial for the correct
functioning of SCHED_DEADLINE.

Add a drgn script for accessing that information at runtime, so that
it's easier to check and debug issues related to it.

Juri Lelli 9fdb12c88e tools/sched: Add root_domains_dump.py which dumps root domains info
Root domains information is somewhat hard to access at runtime. Even
with sched_debug and sched_verbose, such information is only printed
on kernel console when domains are modified.

Add a simple drgn script to more easily retrieve root domains
information at runtime.

Since tools/sched is a new directory, add it to MAINTAINERS as well.
