In a multi-node couch deployment, it was observed that the Service['stunnel']
would be activated, and then later a stunnel::client was created which would
trigger an Exec['refresh_stunnel']. Because of this, and the ordering hints
that were in place, the service would get started, and then the couchdb
databases, users, designs, etc. were being put into place and then a stunnel
client was created, triggering the refresh_stunnel exec, which would cause
an interruption in the connectivity and result in failures.
This change replaces the Service['stunnel'] hint with the the
Exec['refresh_stunnel'] to make sure that the stunnels are fully setup before
attempting couch operations.
