Avoid setting a default value for completionTimeoutPerGiB

[iholder101]

What this PR does / why we need it:
This PR serves two purposes:

1. Align with the changes done in Reduce default CompletionTimeoutPerGiB from 800s to 150s kubevirt#12848.
2. More generally, this is a step forward to eliminate non-essential defaults set by HCO which is an anti-pattern if not a bug. See more info in Remove non-essential defaults from HCO #3163.

Release note:

NONE

Please notice that is going to work only for new installations but it's not going to work for upgrades.

I'm even not sure that keeping it undefined is the best way to handle it.
