tools: Add embargo tool
The existing embargo tool did lookups of the kernel status on the
maintainers' status pages. This no longer works with the new
development workflow and a new tool had to be written to use
brew queries for embargo status.
This new tool has three modes of operation. It can do a search
based on the OS version (8.5, 7.9, etc.), a kernel nvr
(kernel-4.18.0-123.el8), or output information about all OS
versons (using the 'all' option).
