Test case covering logging into existing cluster

We would like to cover basic workflow when user is logging into a cluster.

@lgrossma pointed out that we already have this at

vscode-openshift-tools/test/ui/suite/component.ts

Line 48 in 7feb218

it('Login with credentials', async function() {

. I guess it's just a matter of how to provision a cluster in GH for login to properly be tested, if we can even provision on GH.

I'll take a look into fixing up and running this suite this upcoming sprint. I think the integration tests and the UI tests that require a cluster are run in the same Jenkinsfile
