 A Couchbase connection string is a comma-delimited list of IP addresses and/or hostnames, optionally followed by a list of parameters.
 
 The parameter list is just like the query component of a URI; name-value pairs have an equals sign (`=`) separating the name and value, with an ampersand (`&`) between each pair.
