Merge branch 'rename_license_template_api' into 'master'
Rename Licenses API to License Templates API
## What does this MR do?
Earlier I renamed this in EE, thinking license templates was an EE-only feature. This backports that change to CE. Thanks to @vsizov for pointing out this error.
See gitlab-ee!400 for the EE merge request.
