Fix es.log-level behaviour

Which problem is this PR solving?

• setting logging level #3658

Short description of the changes

• Fixes the es.log-level config setting, which was hard coded to zap's Debug logging level for all es.log-levels.
• This resulted in some debug logging appearing when es.log-level is set to error.
• The fix results in no logs appearing if both log-level and es.log-level are set to error, which seems to be more desirable behaviour. Other es.log-level behaviour remain unchanged.

Testing

• Start collector with log-level=error and (send a single trace) with...

  • es.log-level=error
    Before
    Was zap.DebugLevel logging elastic error logs.
