Delete OCP cluster leftovers using openshift-installer

[oharan2]

Main changes:

• Make filtering more strict by deselecting a group of cluster-related resources if one of them has recently modified
• Update Dockerfile to install the openshift-installer, for local env check if exists
• Update cli with a --yes, -y flag to bypass prompt questions before cluster destroying
  • Otherwise handle user input with [Y/N]
• Added LeftoverAWSOcp class that holds OCP cluster with all it's collected metadata and filtered resources
  • Modified other oop hirarchy for OCP cleanup
• Write down a temp metadata file as an input for the installer:
  • Get the most accurate metadata by extracting OCP's resources tags
• Update the dry run log with printing the names of the OCP clusters with associated leftovers found:
