Status update should not requeue request for the reconciliation

[mnkg561]

Is this a BUG REPORT or FEATURE REQUEST?:
BUG REPORT

What happened:
As part of this PR [https://github.com//pull/82] testing, we found that there is a delay in setting the status of IamRole resource and due to that same request comes again with the status "" instead of Ready which makes IamRole creation again. Apart from the fact, how to gracefully handle that scenario which is being take care in #82 but the issue in the first place is that the request came back for reconciliation. That is due to the fact that resource status got updated and that resulted in a requeue. We already implemented predicate function to ignore the reconciliation for the status update but looks like it is not working as expected.

What you expected to happen:

Status update should not result in reconciliation event there by a delay in setting iam role status should not impact the IamRole creation.

How to reproduce it (as minimally and precisely as possible):
Its an intermittent issue but attaching the logs

Anything else we need to know?:

Environment:

• iam-manager version
• 0.0.6
