IBM deployment fixes

[Tansito]

Summary

We are preparing a deployment in IBM for this project. In our tests with discovered a couple of issues related with our current configuration that this PR tries to mitigate. List of changes:

• New pvc to be used with a cos instance
• Fixed deployment configuration for gateway to work with IQP
• New entity in values to start working with cos

let's also fix image pull policy here (I think it is set to Always right now)

hmmmm, what happened with tests?

tests pass on main, though the unauthorized message pops up there as well...

  congratulations :) (33.75 seconds)

edit: the PR branches passes locally now too... maybe it was just a flake? this one needs a rebase anyways, so on the next commit hopefully it rights itself

Tests should be working fine now :)

I think I solved most of the comments, @akihikokuroda , @psschwei , @IceKhan13 . I tested it and for me it's working, let me know if you find any problem. Related with:

let's also fix image pull policy here (I think it is set to Always right now)

I checked that all our policies are using IfNotPresent.
