Bug 33145: Fix ERM swagger specs

This patch adds the missing 'Provider name' parameter definition to the
various ERM paths that were missing it.

Test plan
1) Run:
   docker run --rm -v $PWD/api/v1/swagger:/swagger \
          jeanberu/swagger-cli \
          swagger-cli validate swagger/swagger.yaml
=> FAIL: The spec is not valid!
2) Apply this patch
3) Repeat 1
=> SUCCESS: Tests pass!
