sbroad needs to be updated to the version that supports newer
tarantool-module

sbroad support for new module version was merged here:
https://git.picodata.io/picodata/picodata/sbroad/-/merge_requests/355

The problem lies in nix package which references memfd_create libc symbol 
which doesnt exist in older libc versions available in centos and astra.

The solution is to patch nix to the state of previous version which uses
raw syscall.The offending commit that broke nix for us is:
https://github.com/nix-rust/nix/commit/cf15c2bb5505231bc3128ef61522336e315e2169#diff-17f9119515eead05b2e65afe0b31095ec95425112c31fe3c529a02f46528b970R56

Another instance of the problem in the wild:
https://github.com/lucab/libsystemd-rs/pull/144

The patch uses nix version 26.4 while the latest one is 27 because rustyline
didnt update to 27 yet and keeping two patched versions doesnt make sense.

So this is our fork with the patch: https://git.picodata.io/picodata/picodata/nix/-/tree/fix-memfd-create-for-older-libc-backport-26-4
And upstream PR: https://github.com/nix-rust/nix/pull/2146

In the long run nix doesnt look like a stable option. There is no libc version
compatibility policy at the moment. The way symbols are used makes them
required even if we're not using them. The alternative, rustix uses weak
symbols or falls back to raw syscalls:
https://github.com/bytecodealliance/rustix/blob/b08519f046787b93121214622aac015b68733c8f/src/backend/libc/fs/syscalls.rs#L1631
I believe with this solution we wouldnt have had this problem in the first
place. There is an open issue in rustyline with suggestion to use rustix
instead of nix: https://github.com/kkawakam/rustyline/issues/733

Allow connecting interactive console over a unix socket `picodata run
--console-sock`. Use `picodata connect --unix` to connect.

This patch introduces `picodata connect` CLI command. It allows
connecting to interactive lua console of a picodata instance via iproto
The whole implementation comes down to invoking a lua script with
`require("console").start()`.

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

1. Encapsulate topology access in a dedicated function.
2. Remove obsolete CachedCell

replication_factor now goes into cluster_state

It prints the raft log in a concise and readable way

Initially, JoinResponse was supplied with every single peer in cluster.
If the cluster is big enough, it results in the "max tuple size limit
reached" error. In fact, only voters are needed for the raft to
operate normally.

Previously the discovery algorithm would try to reach each known peer
sequentially requiring each consequent request to succeed until the next
one can be attempted. This would not work in some cases (see test in
previous commit).

So the new algorithm instead makes a single attempt to reach each peer
within a round, and if some failed they're retried in the next round of
requests. This allows overall discovery to succeed in cases when some
of the initial peers never respond.

Closes #54
