Teardown Lambda function CloudWatch logs

[ashley-evans]

Value Added

Reduces overall AWS costs and confusion when trying to find appropriate CloudWatch logs

Description

Currently the logs that are created during a lambda function's execution are created in an automatically generated log group. Unfortunately, this log group is currently not being torn down by the teardown.sh script.

Therefore, changes should be made to remove these redundant logs once a stack has been torn down.

Acceptance Criteria

AC01

• When the teardown script is invoked, the Cloudwatch logs related to each of the lambda functions within the stack being torn down should be removed

AC02

• No other log groups from other stacks should be removed
