Migrate apps to support host-ip per port (part 1)

[stavros-k]

This PR have to be merged AFTER TrueNAS Fangtooth is released. So the migration can be run.

Closes #787
Closes #791

TODO:

• Add this on migration.yaml on each app

from:
  max_version: <last version before migration>

For automating the above, right before merging,
loop over the apps on master branch, and generate dict of train/app: curr_version
switch to this branch, mass edit an uncomment the placeholder
loop over the apps and replace the from.max_version with the train/app: curr_version
