## Purpose of this PR

## Changes
- Remove `AbstractDB`
- Implement `close()`
## Reference
- [Issue](https://github.com/tursodatabase/limbo/issues/615)
Closes#946
## Purpose of the PR
- As bindings/java is just a library, we shouldn't have to add specific
library dependency(such as slf4j) to itself
- In order to load bindings/java to 3rd party software(such as
Datagrip), we shouldn't provide a library with slf4j included
## Changes
- Remove slf4j, logback dependency and files
- Add custom logger implementation
## ETC
We can now connect to Datagrip(but there are some errors though)

# The purpose of this PR
- Current implementation forces users to use logback as their logging
framework
# Changes
- Only add abstraction layer for loggin(which is slf4j in this case)
- In tests, use logback to log out messages(this doesn't affect the
users)
