future compatibility

[rmader]

Hej, I'm opening this as a tracker bug for errors and warnings with new salt versions. I'll try to have some PRs ready, soon, but first I wanted to have a list. Please comment if you find more

Currently we've got the following tasks:

• update all module.run occurrences to new version (see below) never mind, this is way to new and the fix makes it incompatible with 2017.7 stock version (the new format is only supported if explicitly turned on)
• fix pylxd warning on Ubuntu 18.04
• 'module' object has no attribute 'which' on 2018.3.0 (Oxygen) #12

With salt 2017.7 on Ubuntu 18.04 I'm getting the following warnings on container creation:

[WARNING ] The function "module.run" is using its deprecated version and will expire in version "Sodium".
