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.

In previous implementation Inner Ring allowed storage nodes with any
state to register in the network. According to the current design, only
nodes with ONLINE state are allowed to enter the network map.
Create new `state` sub-package of `nodevalidation` package of Inner Ring
application. Define `state.NetMapCandidateValidator` type and provide
`NodeValidator` interface required by the Inner Ring's processor of
`Netmap` contract's notification events. Embed new validator into the
one used by the Inner Ring application.
From now all `AddPeer` notifications with node state other than `ONLINE`
will be denied.

Add `CompositeValidator` that wraps
`netmap.NodeValidator`s and implements
`NodeValidator` interface itself.

Make `Validator.VerifyAndUpdate` method to return an error if at least one
of LOCODE-derived attributes is set explicitly. Thus, IR will not confirm
the candidates for the network map who independently set these attributes.
Cover `Validator.VerifyAndUpdate` method with unit tests.

Previously UN-LOCODE attribute was required for each network map candidate.
In the absence of this attribute, the candidate was not allowed into the
network map. After revising the requirements for candidates, it was decided
not to require the mandatory installation of the attribute by candidates.
From now inner ring does not modify location attributes of the network map
candidate in the absence of UN-LOCODE attribute and does not block entry
into the network map for this criterion.

Define a structure for dealing with the geographic location of nodes.
Implement VerifyAndUpdate (with the same purpose as NodeValidator interface)
that checks LOCODE attribute and fills other attributes of the location.
Technically the entity is a wrapper over the NeoFS location database: it
maps the node LOCODE to the database record from which the new attributes
are generated.
