Docs/mm/damon/maintainer-profile: introduce HacKerMaiL

Patch series "Docs/mm/damon/maintaier-profile: document a mailing tool and
community meetup series", v2.

There is a mailing tool that developed and maintained by DAMON
maintainer aiming to support DAMON community.  Also there are DAMON
community meetup series.  Both are known to have rooms of improvements
in terms of their visibility.  Document those on the maintainer's
profile document.

This patch (of 2):

Since DAMON was merged into mainline, I periodically received some
questions around DAMON's mailing lists based workflow.  The workflow is
not different from the normal ones that well documented, but it is also
true that it is not always easy and familiar for everyone.

I personally overcame it by developing and using a simple tool, named
HacKerMaiL (hkml)[1].  Based on my experience, I believe it is matured
enough to be used for simple workflows like that of DAMON.  Actually some
DAMON contributors and Linux kernel developers other than myself told me
they are using the tool.

As DAMON maintainer, I also believe helping new DAMON community members
onboarding to the worklow is one of the most important parts of my
responsibilities.  For the reason, the tool is announced[2] to support
DAMON community.  To further increasing the visibility of the fact,
document the tool and the support plan on DAMON maintainer's profile.
