7c3f828893 [#219] metabase: Count parent references in Delete operation
Delete operation of Metabase is performed on group of objects. The set being
removed can contain descendants of a common parent. In the case when all
descendants of a parent object are deleted, it must also be deleted from
the metabase. In the previous implementation, this was not done due to the
chosen approach to counting references to the parent.

e03d906cb7 [#334] engine: Make tests more predictable
There is a codecov issue because objects are not placed
in the engine the same way every unit test. Therefore
sometimes there are more coverage, sometimes there are

4e7d49791b [#199] Index parent first in metabase
With exist check we should index parent first, because
as soon as child will be added to metabase, exist on
parent will return true even if it was not indexed yet.

Also this commit makes one db.Update instead of two for
parent and child.

03fed8ca59 [#160] Update metabase with new root and phy flags processing
Now root and phy (leaf) filters work like flags. They work with
any matcher and any value. So meta-storage sets `true` value for
all root and phy objects and puts them into separate bucket.

We also do not work with inversion anymore, so it either added
to the bucket or not. We don't need to store both options.
This is the reason `selectAll` function is changed a bit. Now
it performs some low-level parsing from primary bucket and root
bucket.
