added stunnel config for bigcouch communication
working on stunnel for bigcouch clustering
moved generic stunnel config from site_webapp to site_stunnel
shorewall couchdb config: get open ports right
moving generic stunnel config from site_webapp to site_stunnel now working
added bigcouch.conf as incoming stunnel config for bigcouch clustering
make site_stunnel::clients connect_port configurable
addded client side of bigcouch cluster protocol stunnel config
add stunnel hiera values to provider_base/services/couchdb.json for bigcouch cluster protocol
increase stunnel verbosity until everything is running smooth
updated shorewall dnat hiera values for bigcouch cluster protocol
added site_shorewall::dnat to configure DNAT rules
added site_shorewall::couchdb::bigcouch

bigcouch cluster protocol communicate via the fqdn of
the neighbor hosts. So we need to bend all requests to
<fqdn>:4369 to localhost:400x (which is the entry of
an stunnel connection to the other neighbor)
couchdb hosts include site_shorewall::couchdb::bigcouch
decrease stunnel debug level
provide stunnel connect_port to site_webapp:couchdb
fix bigcouch stunnel pid name
start erlang vm on dedicated port so firewalling is easier
remove duplicate 'include site_stunnel'

this already exists in class site_stunnel::setup which is instantiated in this
class
shorewall: add couch_server stunnel port to macro.leap_couchdb, this is necessary for the stunnel to communicate
