Configmap from files

[MkrierPharmanity]

Hi

Currently in my applications have high number of env variables requirement read from a .env files and its painful to adding one by one to my cdk8s files.

Before cdk8s i was using the "--from-env-file" options of the "kubectl create configmap" command resulting in a configmap.yaml that i have all the variables of the env file writted to the data property ( cf : https://dulaj.medium.com/kubernetes-env-file-to-config-maps-and-secrets-5bfdb37d8934 for a better explaination if i'm not clear )

After discussing with @iliapolo in Slack , currently there is no simple way to do that with the cdk8s API, adding a "AddPropertiesFile" function to "cdk8splus25.ConfigMap" object will be a great feature
