Bug 1924211

Description of problem (please be detailed as possible and provide log
snippests):
=========================================================================
RGW pod is not deployed with latest OCS 4.7.0-249.ci build. Rook logs show this snip:

2021-02-02 19:08:22.143697 I | ceph-object-controller: object store "ocs-storagecluster-cephobjectstore" deployment "rook-ceph-rgw-ocs-storagecluster-cephobjectstore-a" started

Some background: 
---------------------

From builds >4.7.0-241.ci and below 4.7.0-248.ci, OSD pod creations were failing due to Bug 1922108. With new build 4.7.0-249.ci, though OSD pods are deployed (fixed bug 1922108), RGW pod deployment is now failing.

P.S: RGW pods were deployed successfully till 4.7.0-241.ci build

Version of all relevant components (if applicable):
=======================================================
OCP  = 4.7.0-0.nightly-2021-01-31-031653
OCS = ocs-operator.v4.7.0-249.ci

Does this issue impact your ability to continue to work with the product
(please explain in detail what is the user impact)?
===========================================================================
Yes. In the absence of RGW, even Noobaa backingstore creation failed.

Is there any workaround available to the best of your knowledge?
==================================================================
No

Rate from 1 - 5 the complexity of the scenario you performed that caused this
bug (1 - very simple, 5 - very complex)?
========================================================
3

Can this issue reproducible?
=================================
Tested once

Can this issue reproduce from the UI?
=========================================
OCS installed from UI

If this is a regression, please provide more details to justify this:
=======================================================================
Yes. RGW pods were created successfully for the last accepted build - 4.7.0-241.ci

Steps to Reproduce:
========================
1. Create OCP 4.7 cluster
2. Install OCS 4.7.0-249.ci using UI
3. Check for PODS, Noobaa backingstores


Actual results:
==================
1. RGW pod is not created due to exceeded length of character in the name of deployment.apps 

2. Due to absence of RGW, noobaa deployment is also affected as default Backingstore is not created.


Expected results:
====================
RGW pod should be deployed.
