sysutils/py-azure-cli: Update to 2.0.72

• Port changes
  
  Almost all sysutils/py-azure-cli-* ports were incorporated into py-azure-cli.
  
  This update replaces all those dependencies to their devel/py-azure-mgmt-* port directly, eliminating a level in the dependency chain.
  
  sysutils/py-azure-cli --> sysutils/py-azure-cli-XYZ (GONE) --> devel/py-azure-mgmt-XYZ
  
  Now we will be able to remove ~50 sysutils/py-azure-cli-* ports from the ports tree.

• Add patches to fix an issue with the Policy API >>> ImportError: cannot import name 'PolicyMode'
