Allow cert.pem in dev mode, and do devmode setup regardless of config source
Allow cert.pem in dev mode, and do devmode setup regardless of config source

Dev mode used to be guessable by "Are we not using etcd" but that's no longer the case, we've had an env var for dev mode for a while, so gate the setup logic using that, and allow it to run even if we are using etcd (and especially when we are not!)
Also, cert.pem processing is no longer limited to only etcd launches, so make that contingent on the presence of the cert in /etc/cert/cert.pem rather than limiting it only to etcd launches.

Note that this change requires the root PR that introduces the COUCHDB_HOST_AND_PORT env var when running locally
