Current behavior:

Currently the only way to export server data is to copy/paste it out of the portal or to use the API. Copy/pasting does not give you the ability to control which fields you are exporting, and using the API requires some basic knowledge on scripting/writing code. Neither of these options are great, we should provide the ability to let a user export server data.

Expected / new behavior:

User can export server data to csv. Traffic Portal would allow them to choose servers from a specific CDN, Cache group, etc as well as letting the user choose which fields they want to export. This would be useful for external groups that use the Traffic Ops data for other purposes (e.g. network monitoring)

Minimal reproduction of the problem with instructions:

Anything else:

Does "server data" include associated Profile/Parameters and/or Delivery Service assignments?

Not as part of this issue, this is more focused on the actual server object

it's easier to just do this globally for all tables fyi.
