Fixes#1364
Regression fix for issue introduced in storage refactoring (see issue
for more details).
Changes:
1. Add `profiles/` prefix to profile filename passed in to crawler for
profile creation and written into db
2. Remove hardcoded `profiles/` prefix from crawler YAML
3. Add migration to add `profiles/` prefix to profile filenames that
don't already have it, including updating PROFILE_FILENAME in ConfigMaps
This way between the related storage document and the profile filename,
we have the full path to the object in the database rather than relying
on additional prefixes hardcoded into k8s job YAML files.
Note that this as a follow-up it'll be necessary to manually move any
profiles that had been written into the `<oid>` "directory" in object
storage rather than `<oid>/profiles` to the latter. This should only
affect profiles created very recently in a 1.8.0-beta release.
