Based on feedback having both the configuration file and command line
flags for the BlueCat provider will be used. Therefore update the
documentaiton to reflect that the JSON configuration file for the
BlueCat provider is not deprecated.
New configuration options created for setting the DNS deployment type,
as well as the DNS server to deploy. A DNS server name must be provided
and a valid DNS deployment type must be set in order for a deployment to be
initiated.
Currently, the only supported deployment type is "full deploy", however
"quick deploy" and "selective deploy" could be added in the future.
