Network Access description - Add new textbox

[nmacgreg]

People filling out this form may know details about the service like:

• is this is a public-facing service? (and maybe what protocol)
• does it need access to one of our central RDBMS servers?

A text box that jogs their memory would be useful.

Should we mention "Firewall Rules", or is that too granular?
