Bumping this up to Major as this really is a major feature missing from the module.

This is actually critical as this is blocking the stable release.

This patch will add the following changes:

• Add two routing and menu links
• admin/people/delete_people
• admin/content/delete_content
• One Service -Which list out the available content type

What's Not working yet:

• Option to reset the node count.
• Quick delete option.
• Taxonomy route batch delete option yet to be added.

Note: Apply the patch on the simplytest sandbox environment gives an error.

Things changed in this patch:

1. menu link in one place user Development.
2. Checkbox to delete all content.
3. Unwanted services removed for the routing.
4. Add option to delete users by role

Thanks, @sumitmadan.
The suggested changes are done in this new patch.

Thanks for working on this @abhisekmazumdar.
This was long overdue and much needed patch. Really appreciate your work on this and this would really help us to finally make a stable release for this module.
Also, really good work on patch:

   Nice catch!
   Thanks for this.

Suggestions for few changes:

1. diff --git a/.DS_Store b/.DS_Store
   

   I think this was added by mistake.
   .DS_Store is MacOS-specific folder-settings file and is not needed here.

Yikes!!!!
Just realizing that 'administer content' is actually not a valid permission. It's 'administer nodes'.
Totally my fault. Apologies for misleading you in my last comment.

Can you please fix the patch?
Apologies again.

I too missed crossing check it. It's my fault too. I have updated the new patch with the required changes.
Thank You.

Thank you @abhisekmazumdar for your work on this.
Really good job and this would help us to finally make a stable release for this module.
