Define the Azure Endpoint and other site-specific options (#299)

Added the azureendpoint site-specific option as an ipaddress
definition to make it easier for Azure VMs using dhcpcd to get their
WireServer endpoint address.

Added binhex definitions for all otherwise undefined site-specific
options so that site-specific hooks can use them.
