HDDS-12229. Remove Incorrect Warning for OBS Bucket in Namespace CLI Commands

[Gargi-jais11]

What changes were proposed in this pull request?

Currently, when running the ozone admin namespace summary command for an OBS bucket, a warning message incorrectly states that the Namespace CLI is not designed for OBS bucket layout, even though Recon does support OBS buckets.

Steps to Reproduce:

sh-4.2$ ozone sh bucket create --layout OBJECT_STORE /volume1/obs-bucket
sh-4.2$ ozone admin namespace summary /volume1/obs-bucket 

Output we need to fix:

Connecting to Recon: http://recon:9888/api/v1/namespace/summary?path=/volume1/obs-bucket ...[Warning] Namespace CLI is not designed for OBS bucket layout.
Bucket being accessed must be of type FILE_SYSTEM_OPTIMIZED bucket layout or 
LEGACY bucket layout with 'ozone.om.enable.filesystem.paths' set to true.Entity Type : "BUCKET"

This warning was misleading because Recon correctly processes OBS buckets in the namespace summary. The same warning message is displayed for the follwing files:

• FileSizeDistSubCommand

• QuotaUsageSubCommand

• SummarySubCommand

Proposed Fix:

1. Remove or modify the warning message so that it does not appear for OBS buckets.
2. Ensure that the Namespace CLI properly detects and supports OBS bucket layouts.
3. Validate that all affected commands (FileSizeDistSubCommand, QuotaUsageSubCommand, SummarySubCommand) do not display this incorrect warning.

Files Fixed:

• FileSizeDistSubCommand.java
• QuotaUsageSubCommand.java
• SummarySubCommand.java
• NSSummaryCLIUtils.java
• TestNSSummaryAdmin.java

Thanks for the changes @Gargi-jais11.
Since we are removing all references to isNotValidBucketOrOBSBucket() I think we can delete the method as well.

• isNotValidBucketOrOBSBucket()
• isObjectStoreBucket()
