Introduce a Module with a Fast Detachable ThreadLocal Implementation

[sirinath]

Netty has a FastThreadLocal implementation. Can a similar but faster thread local implementation be added to ActiveJ?

The ThreadLocal can have primitive specialisations to avoid boxing.

Following usages can be replaced once introduced: https://github.com/activej/activej/search?q=ThreadLocal

Also ThreadLocalRandom can be replaced: https://github.com/activej/activej/search?q=ThreadLocalRandom

Hello, @sirinath
Thank you for the suggestion! Right now, due to our multithreaded model based on DI-assisted workers, there is practically no multithreading overhead in ActiveJ, in particular, in using ThreadLocal. Nevertheless, it is a good idea to add this optimization in future releases of ActiveJ, so please stay tuned!

Will be availing the for own ThreadLocal
