feat: Allow setting custom karpenter IRSA policy name

[patrickleet]

Description

allow setting custom IRSA policy name separately from custom role name.

You can use irsa_name currently to set them both to the same thing, but there is no way to give them each custom names.

Motivation and Context

My organization has requirements around role and policy names. The module only lets you set a role name currently, and uses that as the policy name. I need to be able to set a policy name, and a role name, and not to the same thing.

Breaking Changes

No. Made it backwards compatible.

How Has This Been Tested?

• I have updated at least one of the examples/* to demonstrate and validate my change(s)
• I have tested and validated these changes using one or more of the provided examples/* projects

• I have executed pre-commit run -a on my pull request

I ran it locally on a project with all combinations of providing names or not.

[bryantbiggs]

you can specify the name you want to use today with irsa_name, no changes are required

[patrickleet]

no you can't

[patrickleet]

you can only name the policy AND the role the same thing - you can not name them differently, which is my requirement

[patrickleet]

@bryantbiggs can you please re-open and merge this - you are incorrect about no changes being required. Thanks.

[patrickleet]

@bryantbiggs can we add this functionality?

[bryantbiggs]

I suppose we can add this - however, its not giving me the option to re-open the PR (button is grayed out)

[patrickleet]

I'll recreate it - thanks

@bryantbiggs rebased and re-opened here: #2480
