Includes:
1. mode change read lock operation in every exported method that r/w the
underlying database;
2. returning `ErrDegradedMode` logical error if any exported method is
called in degraded (without a metabase) mode.

Includes extending listing methods in the Storage Engine with object types.
It allows tuning replication/policer algorithms: container nodes do
not remove `LOCK` objects as redundant and try to fulfill `LOCK` placement
on the ohter container nodes.

It allows keeping all the locked objects safe after metabase
resynchronization. Currently, all `LOCK` objects are broadcast to all nodes
in a container, it guarantees `LOCK` object presence in a regular situation.

1. Remove a layer of indirection for mutex, `ClientCache` is already
used by pointer.
2. Fix duplication of a `AllowExternal` field.

A container node is expected to have full "get" access to assemble the
object.
A non-container node is expected to forward any request to a container node.
Any token is expected to be issued for an original request sender not for a
node so any new request is invalid by design with that token.

Do not lose meta information of the original requests: cache session and
bearer tokens of the original request b/w a new generated ones. Middle
request wrappers should not contain any meta information, since it is
useless (e.g. ACL service checks only the original tokens).

If an external session is provided and is not opened by CLI itself, add
children objects to it too. It fixes "not found" errors when removing a big
object with a predefined session (from a file).

After presenting request statuses on the API level, all the errors are
unwrapped before sending to the caller side. It led to a losing invalid
request's context.

If a `neofs-cli object delete` operation is performing using a bearer token,
add it to the new `HEAD` requests that collects children OIDs.

It was needed before we started to flush during transition to
`degraded` mode. Now it is confusing.

Do not use node's local storage if it is clear that an object will be
removed anyway as a redundant. It requires moving the changing local storage
logic from the validation step to the local target implementation.
It allows performing any relations checks (e.g. object locking) only if a
node is considered as a valid container member and is expected to store
(stored previously) all the helper objects (e.g. `LOCK`, `TOMBSTONE`, etc).

It is not an error: removing virtual object is expected and should be just
skipped. Getting a virtual object with `raw` flag is considered as an
impossible action, all the virtual objects removals will be handled via
their children's removals implicitly.

Currently there is a possibility for modifying operations to fail
because of I/O errors and a new tree to be created on another shard.
This commit adds existence check for modifying operations.
Read operations remain as they are, not to slow things.
`TreeDrop` is an exception, because this is a tree removal and trying
multiple shards is not an unwanted behaviour.
