Subject: [PATCH] Hotfix: Empty sshPublicKeyFiles list crashed finding master
 ip for ide (#452)

* fixed rule setting for security groups

* fixed multiple network is now list causing error bugs.

* trying to figure out why route applying only works once.

* Added more echo's for better debugging.

* fixed remaining "subnet list gets handled as a single subnet" bug and finalized multiple routes handling.

* fixed None bug where [] is expected when no sshPublicKeyFile is given.
