[Improvement] ::Actions::Insights::EmailPoller to be automatically started on foreman-tasks startup, like e.g. LOCE is
Description of problem:
In case ::Actions::Insights::EmailPoller task is stopped (due to whatever error or user (wrong) intervention), (re)starting foreman-tasks service should ensure re-spawning the task.
This feature is already present for ListenOnCandlepinEevents (LOCE) task, as well as for MonitoQueue::Listener one. It should be available also for the last forever-running/pending task in Satellite.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Somehow stop that task, e.g. manually Cancel it
2. service foreman-tasks restart
3. Check if that task is running
An instance of that task type is running or scheduled, most probably it is in stopped/error state.
An instance of that task type should be in scheduled/pending state.
