This PR implements a new provider for the CloudWatch Logs service. This is done with the objective of internalize the implementation of the service and improve the storage of log events.

This new provider uses LocalStack Stores which improves the parity of the service and makes easier to implement changes for future service API updates.

Also, this new provider uses sqLite which improves the storage of log events by using disk storage instead of in-memory, fixing a memory leak issue that occurs in long rung instances of LocalStack when they use services that generate a lot of Log Events.

Changes

New Logs Provider
New LogGroup, LogStream and SubscriptionFilter definitions for the logs Store.
New database helper that handles database and table creation. Also manages the storage of log events

TODOs for this PR

Add integration with CW Metrics.
Fix events id generation.
Implement correctly provider selection.
