fixing typo and improved the create-tags part (#136)

* fixing typo and improved the create-tags part

`$sgidingress--tags` > `$sgidingress --tags` - missing space was causing an error. 
also changed the way on how to give keys and values.

* create SG's in existing VPC

- added some infos on how to create the SG's in an existing VPC.
- fixed a tag attribute to fit the cluster-name
