Terraform plugins should be in a writable directory on different scenarios, or at least configurable

This line:
https://github.com/phnmnl/cloud-deploy-kubenow/blob/master/cloud_portal/shared/deploy.sh#L122

means that the execution process needs to be able write on the / directory, which is a very bad assumption. This should either be prefixed by $PWD/ so that it happens on the working directory or be made configurable (I would suggest the first option though).

Ok, upon better understanding of this, either the -plugin-dir=... needs to be optional or the downloads can be triggered before terraform init inside deploy.sh (optionally as well).

This is all of course for operation inside the EBI Portal
