[FEATURE-REQUEST] Support for Repos using MySQL

**Describe the problem you're proposing to solve**
When using Kaffy on a project with a repo using the MySQL database drivers, everything related to schemas breaks, as MySQL does not support `ILIKE`, only `LIKE`.

**Describe the solution you'd like**
Depending on the repository database driver, `LIKE` (MySQL) or `ILIKE` (PostgreSQL) should be used.

**Describe alternatives you've considered**
none

**Additional context**
I forked kaffy and did the change manually for testing [in this commit](https://github.com/cybrox/kaffy/commit/d86b5f5571e174a67b919b2637727e222f902bff) and it works fine. `ILIKE` is only used in this one place.

I could submit a PR for a dynamic approach based on the repository driver but I think this would collide with https://github.com/aesmail/kaffy/pull/180. Guess it would be best to complete that PR first :)
