feat(managerclient): adds new task type - 1_1_restore

[VAveryanov8]

This adds a new task type for 1-1 vnode restore.
As managerclient is a separate go module, changes into it should be merged first.

Fixes: #4200

Please make sure that:

• Code is split to commits that address a single change
• Commit messages are informative
• Commit titles have module prefix
• Commit titles have issue nr. suffix

I really need to fix #4121..........
But anyway, I would call this task 121restore or topologyrestore or clonerestore something in this direction.
fastrestore just does not tell the whole story and the possible limitations.

[Michal-Leszczynski]

Also, just another idea in terms of #4200.
I don't really like a completely separate command for this restore type, but I get that adding flags to the current restore task might be messy. Can't we just make it a sub-command of the restore task (similar to sctool backup validate)?
Then, scheduling 121restore would look like sctool restore one2one or something similar.
This makes more sense to me, as why would we completely separate those two restore types?
The code can still be separated according to ones needs, it's just about the command layout.

What do you think @karol-kokoszka @VAveryanov8?

[karol-kokoszka]

Let's leave the discussion if we introduce new CLI to the Wednesday planning. It can be quickly changed.

[karol-kokoszka]

Let's name it "1-1-restore" for now.
Please check if it can be defined as a sub-command for "restore".

@karol-kokoszka @VAveryanov8 Just a general comment before merging - do we want to gradually merge the 121 restore changes to the master or to the feature branch?
The changes from native Scylla backup/restore are merged to feature branch.

I would say that we should be merging things to master as it's annoying to keep on rebasing the feature branch. It's also annoying that merging to feature branch does not close fixed issues.

[karol-kokoszka]

It make sense to work on it with the feature branch.
