Fix-bastion-errors

[openoms]

Fixing the errors seen when logging in to the bastions:

• bos completion needs to be sourced, not displayed

• the error needing the gke-gcloud-auth-plugin is displayed when running: kauth:

openoms_galoy_io@galoy-staging-bastion:~$ kauth
Fetching cluster endpoint and auth data.
CRITICAL: ACTION REQUIRED: gke-gcloud-auth-plugin, which is needed for continued use of kubectl, was not found or is not executable. Install gke-gcloud-auth-plugin for use with kubectl by following https://cloud.google.com/blog/products/containers-kubernetes/kubectl-auth-changes-in-gke
kubeconfig entry generated for galoy-staging-cluster.

this needs to be installed with apt

This didn't work before, and I removed it. Debugging it, I found that the apt-add-repo on line 9 wasn't working. Re-adding it without fixing the addition of the repo wouldn't work.

in 6608713 changed the apt key and repo addition to the current recommendation at https://cloud.google.com/sdk/docs/install#deb (works on the bastions), but removed the sudo-s as it is running with root already

left the

apt-get install -y google-cloud-sdk-gke-gcloud-auth-plugin

line separate and last so nothing else will be missing if it fails.

Hope this will work.
