tools: Add tooling for basic cloud-init performance analysis.
This branch adds cloudinit-analyze into cloud-init proper. It adds an
"analyze" subcommand to the cloud-init command line utility for quick
performance assessment of cloud-init stages and events.
On a cloud-init configured instance, running "cloud-init analyze blame"
will now report which cloud-init events cost the most wall time. This
allows for quick assessment of the most costly stages of cloud-init.
This functionality is pulled from Ryan Harper's analyze work.
The cloudinit-analyze main script itself has been refactored a bit for
inclusion as a subcommand of cloud-init CLI. There will be a followup
branch at some point which will optionally instrument detailed strace
profiling, but that approach needs a bit more discussion first.
This branch also adds:
* additional debugging topic to the sphinx-generated docs describing
cloud-init analyze, dump and show as well as cloud-init single usage.
* Updates the Makefile unittests target to include cloudinit directory
because we now have unittests within that package.
