Adding support for disabling liveness and readiness probes to the Helm chart

[njegosrailic]

What this PR does / why we need it:

In some cases, we may want to disable liveness probes but with the current templates, it's not possible. We have tried to override values or to use Command Exec that will always return true but it results in a very strange template.

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• CVE Report (Scanner found CVE and adding report)
• Breaking change (fix or feature that would cause existing functionality to change)
• Documentation only

Hi @njegosrailic. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
