To simply the scripts and to allow easy integration of new monitor types,
restructure the template files as followed:
1. Move the template files to be in the same directory as the rvgen
package. Furthermore, the installation will now only install the
templates to the package directory, not /usr/share/. This simplify
templates reading, as the scripts do not need to find the templates at
multiple places.
2. Move dot2k_templates/* to:
- templates/dot2k/
- templates/container/
This allows sharing templates reading code between DA monitor generation
and container generation (and any future generation type).
For template files which can be shared between different generation
types, support putting them in templates/
This restructure aligns with the recommendation from:
