Add currentSchema to ConnectionPoolConfiguration

I was making a PR to quill and realized I forgot to add currentSchema here.

Please fix the build, right now it fails on formatting. How to fix: https://github.com/jasync-sql/jasync-sql/blob/master/CONTRIBUTING.md#building-locally

Let me know if you need assistance.

/home/runner/work/jasync-sql/jasync-sql/db-async-common/src/main/java/com/github/jasync/sql/db/ConnectionPoolConfiguration.kt:193:39: Not a valid Kotlin file (expecting an argument) (cannot be auto-corrected)

This sounds like an issue with the linter, I am also unable to run it locally.

the linter is from older version that is why you see the error. I will update it someday.
Anyway, I wasn't able to to add changes to this pr, so I added them here: #283
