Close #635

Reasons:
- it's not safe to split raft entries as atomicness is lost
- the original feature was not tested

Previously, we took advantage of a faster psycopg-binary, but this
dependency tends to fall short whenever we produce a bad server
packet, leading to obscure backtraces.

pgproto used to interact with picodata through lua entrypoins, but after
making pgproto a picodata module, we can get rid of this lua layer and
simply call corresponding rust functions.

After moving pgproto into picodata we can merge their implementations of
Describe into a singe module.

The backend module implements the logic for handling postgres messages.
Note that this commit doesn't bring anything new: it just moves picodata's
handlers into pgproto.

chore(plugins): `update_plugin_tiers` API call is split into `service_append_tier` and `service_remove_tier` calls

godzie44 authored 10 months ago and Georgy Moshkin committed 9 months ago

- add description field to `_pico_plugin` and `_pico_service`
- plugin loading: filter files by its extensions
- plugin loading: check possible service collisions
- plugin loading: now plugin searching at {plugin_dir}/{plugin_name} path
- now all errors between plugin and picodata wrapping with `BoxError` (this protects plugin caller from UAF)

This patch fixes a couple of warnings that look like this:

```
warning: creating a shared reference to mutable static is discouraged

   = note: this will be a hard error in the 2024 edition
   = note: this shared reference has lifetime `'static`, but if the static ever gets mutated, or a mutable reference is created, then any further use of this shared reference is Undefined Behavior
help: use `addr_of!` instead to create a raw pointer
