Shard should try to read object headers from write-cache if it is enabled.
Extend `writecache.Cache` interface with `Head` method. Call the method in
`Shard.Head` if `Shard.hasWriteCache` returns true.

Write cache should be able to execute HEAD operations according to spec.
Add simple implementation of `Head` method through the `Get` one. Leave
notes for future optimization.

Caching is performed inside `GetNativeContractHash` method of neo-go client,
so the additional cache level is redundant.

There is no need to continue iterating over Neo RPC endpoints in case of
some address-independent error (e.g. NeoFS logic error).
Unwrap and immediately return `neofsError` errors from loop in
`iterateClients`.

Implement `error` interface on new `neofsError` type which is a wrapper over
NeoFS-specific error. Wrap all `Client` errors except neo-go client API ones
into `neofsError`. Wrapped errors are going to be used for multi-endpoint
loop control.

Since morph `Client` works in multi-client mode, there is an error case when
we can not get network magic when all endpoints are unavailable.

There is a need to work with a set of Neo RPC nodes in order not to depend
on the failure of some nodes while others are active.
Support "multi-client" mode of morph `Client` entity. If instance is not
"multi-client", it works as before. Constructor `New` creates multi-client,
and each method performs iterating over the fixed set of endpoints until
success. Opened client connections are cached (without eviction for now).
Storage (as earlier) and IR (from now) nodes can be configured with multiple
Neo endpoints. As above, `New` creates multi-client instance, so we don't
need initialization changes on app-side.
`Wait` and `GetDesignateHash` methods of `Client` return an error from now
to detect connection errors. `NotaryEnabled` method is removed as unused.

As soon as resulting list and cache operate with the attribute pointer,
we can add attribute structure immediately and set restored key and
value of the attribute later.

Attributes are linked to each other through parents, so they can
be returned in any order. However, it will be better to return
the list in consistent order to reduce entropy.

Parser should reuse existing attributes from the cache to update list
of the parent links in it. Parent links should be unique.

In previous implementation Container service handlers didn't cache the
results of `Get` / `GetEACL` / `List` operations. As a consequence of this,
high load on the service caused neo-go client's connection errors. To avoid
this there is a need to use cache. Object service already uses `Get` and
`GetEACL` caches.
Implement cache of `List` results. Share already implemented cache of Object
service with the Container one. Provide new instance of read-only container
storage (defined as an interface)to morph executor's constructor on which
container service is based. Write operations remained unchanged.

Storage node should not try to register itself in network in relay mode.
Implement `needBootstrap` method which checks if node need to bootstrap.
Call `bootstrap` method in `bootstrapNode` function only on true return.
Skip re-bootstrap logic in new epoch event handler on false return.
Return an error if `ControlService.SetNetmapStatus` is called on relay
node.

Add `refill-gas` sub-command to `morph` command which provides the ability
to refill storage node's GAS.
Command performs some actions from `generate-storage-wallet` runner, so
common code is moved to a separate function `refillGas`.

In previous implementation of Policer's job queue the same list of objects for
processing was selected at each iteration. This was caused by consistent
return of `engine.List` function.
Use `rand.Shuffle` function to compose pseudo-random list of all objects in
order to approximately evenly distribute objects to work.
