Remove usage of docker.sock in anms-core image

Eliminate usage of docker.sock in anms-core image OR document/test instructions to enable usage with podman.

[DavidEdell]

Socket has been commented out in the docker-compose.yml file of the podman branch (dsn-devel). This causes the "Status" page in the UI to be unable to query the status of any services.

Podman does support a compatibility layer to theoretically enable this functionality, however doing so within a nested container adds additional complications, manual system configuration and permission issues.

It is recommended to replace this functionality with a generic health monitor that more directly checks if services are available (ie: by testing TCP connections or REST endpoint availability as applicable). Such an approach would also allow functionality to be preserved if one or more services are migrated outside of the containerization in future deployments.
