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

This commit fixes that non-admin users can't read queries from the query cache.
An attempt to read from the cache used to result in the following error:
sbroad error: failed to get space_def: box error: AccessDenied: Read access to space '_pico_table' is denied for user 'alex3'

Previously, an error would occur when a user ran the same query twice.
During the first execution, the query was prepared and cached. However,
on the second execution, the client attempted to retrieve the query from the
cache and encountered an access denied error.

- we didn't check that index name is unique
in indexes meta table. That led to panics
when index with same name was created for
two tables.
- previous commit set wrong sbroad submodule.
Set sbroad submodule to correct commit
