Automatically detect the names of tables and repositories

[EgorkaKulikov]

Description

Avoid hardcoding the names of tables and repositories: get this data via reflection and bean definitions.

How to test

Automated tests

Please specify the automated tests for your code changes: you should either mention the existing tests or add the new ones.

For example:

The proposed changes are verified with tests:
utbot-fuzzing/src/test/kotlin/org/utbot/fuzzing/FuzzerSmokeTest.kt

Manual tests

If it is impossible to provide the automated tests, please reason why. Usually, it is relevant only for UI- or documentation-related PRs.
If this is your case, share the detailed manual scenarios that help to verify your changes.
