Since now hawkBit support Swagger and OpenAPI the documentation is built
using redoc based on OpenAPI definitions. Spring REST documentation is
not needed anymore.
Since this Spring REST doc is not needed and it duplicates API
documentation (no single source of truth and hard to maintain) with this
commit it is removed.
Some tests from the Spring REST doc that seems are not covered by the
JUnit of the resource modules are moved in the resource JUnit tests.
