Include JSON schema lint in SR test suite

Usually when we make change to SlapOS profiles, we only check the result of SR test and sometimes problems in the json schema are introduced and we only notice this when we check the result of `SLAPOS-EGG-TEST`.

This MR is about:
  - also running `slapos.cookbook` tests as part of `SLAPOS-SR-TEST`. This test in fact contain both "egg tests" for some recipes in nexedi/slapos repository and "lint test" for the formatting of json schemas for parameters (because this nexedi/slapos repository contain both some recipes and profiles).
  - fixing current problems with json schemas on master branch.
