crossing boundaries among schemas/users
When navigating keys starting from L1_HLT_CONF, since there is a crossing of schema, you are prompted to first commit the other changes, before doing anything else. Since it's bound to the table, also changes on the same user's table are not allowed.
This behavior must not be table dependent: it should apply any time there are change of users. Summarizing:
- remove snowflake in L1_HLT_CONF asking for commit
- prompt the request for commit every time a change of user is involved
