Inner Ring should allow registering of storage nodes with `MAINTENANCE`
state in the NeoFS network only if its configuration allows this status.
Make `networkSettings.MaintenanceModeAllowed` to call
`MaintenanceModeAllowed` method of underlying Netmap contract's client
in order to assert state allowance.
From now nodes will be accepted to the network with `MAINTENANCE` state
only with the appropriate network configuration.

There is a need to prevent limitless abuse of MAINTENANCE status of the
storage nodes. To do this, configuration of the NeoFS network is going
to be extended with the flag which allows the state. Until this is done,
it makes sense to prepare a site for this in the code.
Define `state.NetworkSettings` interface as an abstraction of global
network configuration within the `state` package. Make
`NetMapCandidateValidator` to depend on `NetworkSettings` and provide
corresponding field setter. Change `VerifyAndUpdate` method's behavior
to return an error for candidates with MAINTENANCE state if this state
is disallowed by the network configuration. Provide `NetworkSettings`
from the wrapper over Netmap contract's client on Inner Ring application
side. The provider is implemented to statically disallow MAINTENANCE
mode in order to save previous behavior.
