I stumbled across following problem creating custom python ansbile action plugin: how to execute some modules once (i know in yaml it is possible to set run_once and delegate_to)?

For example having following code:

from ansible.plugins.action import ActionBase
from ansible.errors import AnsibleError


class ActionModule(ActionBase):

    def run(self, tmp=None, task_vars=None):

      super(ActionModule, self).run(tmp, task_vars)

      module_args = self._task.args.copy()

      ret = {}

      # create group
      module_return = self._execute_module(module_name='group',module_args={'state':'present','name' : 'bob'}, task_vars=task_vars,tmp=tmp)
      ret.update(module_return)

      module_return = self._execute_module(module_name='user',module_args = {'state':'present','name' : 'bob','group' : 'bob','home':'/nfs/bob' },task_vars=task_vars,tmp=tmp)
      ret.update(module_return)

      # run once this command ????
      module_return = self._execute_module(module_name='file',module_args = {'path':'/nfs/bob','state':'directory','mode' : '0700' },task_vars=task_vars,tmp=tmp)
      ret.update(module_return)

      return ret


Current code will execute file module for every host, but i need to execute that part once.
