Previously after tree split we can have duplicated parts
(several objects and tree node referred to the same part number).
Some of them couldn't be deleted after abort or compete action.

It's need to fit user expectation on deleting CORS for example.
Previously after removing cors (that was uploaded in split manner)
we can still get some data (from other node)
because deletion worked only for latest node version.

Previously if multipart key has the same name as some system node
(e.g. bucket-settings, bucket-cors etc.) it shadows real system node
and bucket started to be unversioned again for example.

Add two strategy for PutBucketSettings request retryer:
* exponential backoff (increasing up to `max_backoff` delays with jitter)
* constant backoff (always the same `max_backoff` delay between requests)

In order not to accidentally take outdated
information about downloaded parts from other
nodes, now when the multipart is abort or complete,
the root node of the multipart upload with the
finish flag remains in the tree.

With new retry policy of tree service pool, gateway should avoid
deletion of system nodes from tree. Absence of node in the tree
will trigger retry. Other storage in the network may return already
deleted node while tree is not completely synced, and client will
get unexpected result.

When the object version is received,
the node of the secondary object may return.
Now we choose the right node ourselves.

Add new flag to object tree meta `isCombined` that means
the object payload is list of parts that forms real payload.
Set this attribute when complete multipart upload not to do unnecessary copying.
