[terraform-resources] module support PoC

[maorfr]

part of https://issues.redhat.com/browse/APPSRE-10573

depends on app-sre/qontract-schemas#686

with this functionality, we can provision resources based on a module in a git repository:

  resources:
  - provider: module
    module:
      url: <repo url>
      path: <path to module>
      ref: <branch or commit sha>
    identifier: my-identifier
    defaults: path/to/file/with/variables.yaml

next problem to fix:

This module is not yet installed. Run "terraform init" to install all modules
