Moving tests on Loaclstack

[semenodm]

I found it would be useful to run all tests agains Loaclstack instead of mocking AWS SDK, KPL, KCL, especially KCL.
However i tried to reproduce stream resharding and found that Localstack doesn't support UpdateShardCount operation, it is not failing, but it does nothing.
I did some search and found following discussions

1. Support Kinesis UpdateShardCount localstack/localstack#654
2. Looks like this is the stub to support API call but it actually does nothing
   add UpdateShardCount support for Kinesis localstack/localstack#1229
3. Add support for UpdateShardCount mhart/kinesalite#61
4. kinesalite is the project used to support Kinesis integration in Localstack, this PR is still open, but looks like feature is implemented
   Added support for UpdateShardCound & DescribeLimits mhart/kinesalite#48

Sounds like a good idea to me. So mhart/kinesalite#103 (which appears to have been open for over 5 months) needs to be merged, then localstack needs to upgrade to the latest version of kinesalite (and some minor code changes are required)?

yeah, i dropped some notes there, to demonstrate what is the problem, hopefully someone merge this work and then we need to remove that stub in Localstack :)

Just following up here. Localstack now uses kinesis-mock, which has this support.
