Docs/mm/damon/design: place execution model and data structures at the beginning 

The execution model and data structures section at the end of the design
document is briefly explaining how DAMON works overall.  Knowing that
first may help better drawing the overall picture.  It may also help
better understanding following detailed sections.  Move it to the
beginning of the document.

Execution Model and Data Structures
===================================
The monitoring-related information including the monitoring request
specification and DAMON-based operation schemes are stored in a data structure
called DAMON ``context``. DAMON executes each context with a kernel thread
called ``kdamond``. Multiple kdamonds could run in parallel, for different
types of monitoring.
