Tidy up - Primitive

Some Python class and packages need to be renamed
for a better compliance with the shared terminology
which provides a better understanding of Watcher
objects and components by every contributor.

This patchset is there to change
Primitive to Primitives.
Add BasePrimitive.

Partially implements: blueprint glossary-related-refactoring
