81722c373b [#746] morph/client: Don't cache GAS contract address on NeoFS-side
Caching is performed inside `GetNativeContractHash` method of neo-go client,
so the additional cache level is redundant.

18c49c2cb9 [#746] morph/client: Break loop in iterateClients on NeoFS error
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`.

ad7ad12a0c [#746] morph: Implement and use multi-client
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.
