      hooks: Provide variables with post-opcode values · dd7f6776
      Michael Hanselmann authored
      When a hook is called, it is provided with a number of variables
      describing the status of the instance/node/etc. before the operation.
      Some opcodes provide extra variables to see modified values from hooks,
      but that's not a generic solution.
      This patch modifies the code calling hooks to generate the environment
      once before and once after an opcode has been executed. Doing so should
      be safe—I did not find any LU.BuildHooksEnv modifying LU instance
      attributes. The values collected after running the opcode are prefixed
      with “GANETI_POST_”, as opposed to “GANETI_” for pre-execution
      variables. The latter are still provided for backwards compatibility.
      Environment variable examples:
      gnt-instance start $instance:
      gnt-instance modify -B memory=512 $instance:
