`Degraded` mode can be set by the administrator if needed.
Modifying operations in this mode can lead node into an inconsistent state
because metabase checks such as lock checking are not performed.

Do not check that a node indeed belongs to the container, because the

Do not return backend type from the service for now, because memory
backend is expected to vanish.

It is nice to have different paths for different components and also
check that the information returned is different for different shards.

`Degraded` mode is set automatically after error counter is over the
threshold. `ReadOnly` mode can still be set by an administrator.

specified). Read allowed keys from config.

Implement `ControlServiceServer` on `Server` type. The `Server` requires all
requests to be signed with keys from the so-called whitelist. To obtain
health status, it uses the abstraction in the form of `HealthChecker`
interface.

Define `ControlService` for IR similar to the one from storage node. Add
`HealthStatus` RPC which returns health status of the IR application.
Implement getters, setters and methods to sign/verify the messages.
