189507dc89 [#1541] neofs-cli: allow to print shards list output in JSON
Eventually more parameters will be supported (#1390) and after blobstor
configuration refactoring the output will certainly change. Implement
the simplest approach now.

Marshaling the result directly results in too ugly names and they cannot
be easily customized. Marshaling the results via `jsonpb` is better but
is not that flexible in terms of what we want to output.

cd545f0160 [#1351] cli: Fix connection scheme loss during endpoint parsing
In previous implementation NeoFS CLI app used `network.Address.HostAddr`
as a server URI, which caused scheme loss since host address doesn't
contain it.

Rename `HostAddr` to `URIAddr` and make it to return URI address with
`grpcs` scheme if TLS is enabled. Make `TLSEnabled` unexported since it
was used to provide default `tls.Config` only (it is used by default in
SDK).
