Implement `sort.Interface` interface on `AddressGroup` and perform sorting
in `AddressGroup.FromIterator` method. Addresses with enabled TLS are "less"
in terms of slice position.

In future server info will contain multiple endpoints whose string
representation will be worse suited to the cache key.

Use `GroupFromAddress` to call the method from the wrappers in order to no

There is a need to generalize single-address client to group-address client.
To do this, we can re-implement `Client` interface from NeoFS API Go library
and still use it in the application code. There is a problem with method
`Raw` which must return single-address raw client. So as not to make changes
to API library we need to overload Client interface in order to support
`Raw` method in group-address client implementation.
Define `Client` interface in new `pkg/core/client` package. Completely
inherit API `Client` interface. Add `RawForAddress` method to build raw
client for the single node address. Adopt the application code that used Raw
method to work with new `Client`.
