(lambda): Provide a way to specify a log group for a lambda function

[kastork]

Provide a way to specify a log group for a lambda function.

Use Case

In my environment, security policy prevents the deletion of log groups and streams by normal system operators.
When developing, it is common to deploy the lambda many times, and in this environment, that means every deployment creates a new log group.

I'd like to treat the log group in a logical way by saying "for this function, the logs are always at this location"

I do this by creating the log groups separately, as a high level system feature, then deploy applications that use them.

Proposed Solution

This is as of Typescript CDK version 1.75.0

Currently, CDK does allow you to retrieve log groups, but it does not allow you to set the retrieved group as the log group for the lambda function.

I suggest that the Function construct have an optional constructor parameter to set this.

Unfortunately, this is not possible. The location of the logs for a lambda function is determined by the lambda backend service. Last I checked, they do not provide an option to specify/change this.
