Add LocationType Specification to DNA Center and Device42

[jdrew82]

This PR is to update the DNA Center integration to add the capability to specify the LocationType for each of the types of location objects that are imported. I've also added the missing User documentation along with screenshots for how to use the integration and steps to add the required pieces.

I see some device42 commits in here, is this intended?

Yeah, that's intentional. I figured might as well update any of the integrations that could benefit from the option.

It would be helpful to show the locationtype in parenthesis next to the three locations on the top right panel here.
