Replace swagger doc gen with commmon approach

Replace swagger doc gen with commmon approach

The swagger documentation generation is moved to policy-parent. This
commit removes the CLAMP swagger document generation and replaces it
with the common handling.

It also fixes the following bug:
The current CLAMP build generates the swagger.json file using a unit
test case. That file is used later in the build to generate a
swagger.pdf and swagger.html file. If the tests are skipped, the
swagger.json file is not generated and the build fails on the PDF/html
generation step.

This change adds a profile to the build that only does the PDF/html
generation when the skipTests flag is off.
