Docs/admin-guide/mm/damon/usage: link design doc for details of kdamond and context 

The explanation of kdamond and context is duplicated in the design and
the usage documents.  Replace that in the usage with links to those in
the design document.

kdamonds/
---------
The monitoring-related information including request specifications and results
are called DAMON context. DAMON executes each context with a kernel thread
called kdamond, and multiple kdamonds could run in parallel.
Under the ``admin`` directory, one directory, ``kdamonds``, which has files for
controlling the kdamonds exist. In the beginning, this directory has only one
file, ``nr_kdamonds``. Writing a number (``N``) to the file creates the number
of child directories named ``0`` to ``N-1``. Each directory represents each
controlling the kdamonds (refer to
:ref:`design <damon_design_execution_model_and_data_structures>` for more
details) exists. In the beginning, this directory has only one file,
``nr_kdamonds``. Writing a number (``N``) to the file creates the number of
child directories named ``0`` to ``N-1``. Each directory represents each
kdamond.
