Deployment enhancements

[landonreed]

After some pained troubleshooting, we've identified the following enhancements for deployments in order to make troubleshooting and finding deployments a little easier:

• show routerId so user knows if this is a 'test' feed or main production feed
• we should look for outlier stops and report them as a validation warning
• the deployment screen should show a preview of the OSM extract area as a map. (maybe even allow adjustment on the fly?)
• there doesn't seem to be any rhyme or reason to how the deployment listings are sorted. I would have it default to deployment data (most recent first), with maybe an option to sort by name
• maybe also allow sorting by any of the columns in the main feed source list. e.g. if you want all of the deployable feeds on top
• it would also be handy to have some indication of when the feed was last updated in that list
• if feeds are removed from the deployment because they are expired, there should be a warning for the user
• option to use cached OSM file and/or bundle (skip downloading)
• notify the user when the deployment to server completes or fails
