Allow non-admin to manage SQL scripts

**Is your feature request related to a problem? Please describe.**
CloudBeaver is great for centralized all db connections. My team is hoping to share SQL snippets within a team so that other people can lookup and reuse them without wasting time looking for schemas. This benefits when team do oncall rotation and onboard a new team member.

Currently, CloudBeaver only allow admin of the instance to manage SQL snippet which is in-practical and it blocks team from contributing shared SQL snippets.

**Describe the solution you'd like**
For a basic use case, CloudBeaver should have a setting to allow anybody (logged in user) with a permission to manage SQL snippets.

For more a advanced setting, each folder can be assigned to a group with read-only or read-write permission.
