[TC-32] Addition of ATS Config API

[dg4prez]

Working API for ATS config file generation, divided by three "scopes" - CDN, profile, and server.

This is intended to be used for a redesign of the ATS config process. No test files have been generated yet - this PR is intended for review only, and is linked to https://issues.apache.org/jira/browse/TC-32

Should be ready for test and merge.

i thought you got rid of "scope" parameters?

[dg4prez]

yeah, i did. missed that lookup.

There have been several changes to ConfigFiles.pm since this PR was submitted:

git log traffic_ops/applib/UI/ConfigFiles.pm

so you might want to makes sure those changes are addressed in the PR...
