upgrade: demonstrate that a no-op upgrade still performs everything
An upgrade operation which is not adding or removing anything should ideally
error out. However, it does the whole cloning and everything. Next patch will
fix it.

upgrade: remove unnecessary `is None` check
`upgrade_engine.upgrade()` always return the `backuppath` value and there are
not early returns. Hence I don't see how `backuppath` can be None.
Adding extra unncessary safe checks hides unknown bugs. Hence removing it.

engine: refactor code to replace stores in separate function
In not all upgrades, we need to change the whole store. For example, when
upgrading repository to share-safe mode, we don't touch revlogs at all hence
store cloning and copying is not required.
The store replacing code needs to be made aware about what all has changed and
hence only copy/rename those things. To kickstart that, this patch moves
existing logic into a separate function.

engine: make hook point for extension a public function
Well there are no private public functions in Python, but we generally treat
functions and variables starting with `_` as private ones.
A function which needs to be overrided in extension should be a public one.

engine: prevent multiple checking of re-delta-multibase
The _perform_clone function is called for each revlog cloned, hence we should
prevent this function call overhead.

engine: pass upgrade operation inside _clonerevlogs()
Better to pass the operation instead of passing three of it's members (one of
the them is a function call) separately.
This will also be useful in future when we will like to control which things are
upgraded.

actions: store deltareuse mode of whole operation in UpgradeOperation
UpgradeOperation should provide easy access to all the things related to the
current operation. Clients should not need to compute them.

engine: refactor how total dstsize is calculated
Instead of increasing it with each revlog, we just get the sum of total
destination changelog, manifest and filelogs sizes.
