EVM Server Main Configuration are not being passed to refreshers.

[jvlcek]

When defaults are changed in the EVM Server Main Configuration file via
Configure/Advanced the changes are not being passed to the Refreshers.

This can be observed using the rails console on an appliance with:

  e = ManageIQ::Providers::Amazon::CloudManager.first
  r = ManageIQ::Providers::Amazon::CloudManager::Refresher.new([e])
  r.refresher_options
  # => nil

That should not be nil.

Something is preventing the options from being passed to the refreshers.

This is related to the issue reported [1] where gathering EC2 public images fails even
after the default is changed from:
get_public_images: false to:
get_public_images: true
