Exclude common documentation from its-base artifact

Currently the common documentation is provided in this base library,
that is overridden by different its provider plugins. To prevent the
plugins to exclude the common documentation filed in their build tool
chain, move these files from resources to templates directory.

This way the its provider plugins wouldn't need to strip these files
in their build implementations.

Test Plan:

  $ bazel build its-base
  $ unzip -t bazel-genfiles/its-base.jar | grep Documentation
    testing: Documentation/
    testing: Documentation/config.md
    testing: Documentation/config-rulebase-common.md
    testing: Documentation/config-common.md
