Eliminate code duplication, use `define_str_enum` macro from tarantool-module.
Remove personalized `FromStr::Err` for every enum defined that way.

Cases covered:
- when someone goes offline
- whenever vshard gets reconfigured

Currently stores:
- replicset_id
- replicaset_uuid
- sharding weight
- replication master id

Every field of Peer now has a corresponding unit struct defined in the
`peer_field` module, which implements the `PeerFieldDef` trait which in
turn contains information about the field's name, tarantool type and
rust type.

This information currently is used in the `field_by_raft_id` method
and is generated by the `define_peer_fields` macro, which also
automates the generation of the format (`peer_format` function) for the
"raft_group" space.

replication_factor now goes into cluster_state

If makes the code neater.
