Closes #9614

Change Description

Remove unused Adapter.Remove method from the block adapter interface and all its implementations.

Background

The Remove method in the block adapter interface was not being used anywhere in the codebase except in tests. As mentioned in issue #9614, this makes issue #6836 (which was about optimizing the S3 Remove implementation with wait/verify logic) meaningless since the method is never actually called in production code.

This PR removes:

• The Remove method from the Adapter interface
• All implementations across adapters (S3, GCS, Azure, Local, Memory, Transient)
• The metrics wrapper for the Remove method
• The test function testAdapterRemove

This simplifies the codebase and removes approximately ~230 lines of dead code, including the expensive waiter.Wait operation in the S3 adapter that was waiting for object deletion confirmation.

Bug Fix

N/A - This is a tech debt cleanup, not a bug fix.

New Feature

N/A - This PR removes code rather than adding new features.

Testing Details

1. Verified that Remove method is not called anywhere in production code using grep searches
2. Confirmed successful compilation of all block adapter packages
3. Verified no linter errors after changes
4. The only references to Remove were in test code, which has been appropriately removed

Breaking Change?

Technically yes - this removes a public method from the Adapter interface. However, the method was not used anywhere in the actual codebase (only in tests), so there should be no practical impact on existing functionality.

Impact:

• ✅ API: Method removed from interface (unused in practice)
• ✅ CLI: No impact
• ✅ Clients: No impact (method was not exposed to clients)

The sort import was removed, but sort.Strings(tree) is still used on line 270 in the dumpPathTree function. This will cause a compilation error.

The sort import should not be removed.

Suggested change

	"path/filepath"
	"path/filepath"
	"sort"

[Copilot]

The testGetProperties function is being removed here, but it's still called on line 28 in the AdapterTest function. This will cause a compilation error.

Either keep this function, or remove the call to it from line 28.

Thank you for your contribution!

Thank you so much for this, @potapovkd! There's a MockAdapter implementation that also includes this method which we should remove, along with the error variable it returns. Other than that, it looks great!

It seems like we have some CI configuration issues where a necessary secret isn't being passed to forked repositories. I'll look into this with the team and make sure we get the tests running :)

@zubron thank you! I removed this method from the MockAdapter implementation

[zubron]

Thanks for tidying up that last bit, @potapovkd! I tested your changes in another PR and it was all good 👍
