Feature request: SSM parameters to look up layer ARNs

[sthulb]

Use case

I would like to be able to dynamically lookup the latest available AWS Lambda layer ARN.

Solution/User Experience

AWS has already been maintaining a list of public SSM parameters, please consider enlisting powertools-lambda-python too. Similar to ref. https://aws-sdk-pandas.readthedocs.io/en/latest/install.html#aws-lambda-layer

$ aws ssm get-parameters-by-path --path /aws/service/list
$ aws ssm describe-parameters --parameter-filters 'Key=Name, Option=BeginsWith, Values=/aws/service/aws-sdk-pandas/' --query 'sort_by(Parameters, &LastModifiedDate)'

Sample code

powertools_layer_arn = ssm.StringParameter.from_string_parameter_attributes(self, "MyValue",
  parameter_name="/aws/service/powertools-lambda-python/x.y.z/py3.xx/x86_64/layer-arn"
).string_value

Alternative solutions

Hardcoded Lambda layer ARN

Acknowledgment

• This feature request meets Powertools for AWS Lambda (Python) Tenets
• Should this be considered in other Powertools for AWS Lambda languages? i.e. Java, TypeScript, and .NET
