This commit embeds in plugins a new variable, containing picoplugin
version used to build it. If this version differs from the picodata version
when the plugin gets loaded, the loading fails with an error reporting
the expected and the current versions. This check can be disabled via env
PICODATA_UNSAFE_DISABLE_PLUGIN_COMPATIBILITY_CHECK.

New argument `--timeout` for `picodata expel`.

New argument `--timeout` for `picodata connect`.

This moves most of the logic from the supervisor process which helps
with a number of problems with the main_cord stuff. For example in a
following commit the context will only be parsed in tarantool::main_cb
which means config parameters aren't accessible in supervisor.

This also moves us towards getting rid of the supervisor process in the
future.

use split_once instead split

Supported in:
picodata admin (lua/sql mode)
picodata connect

this fixes the following bug:
```
picodata run --data-dir tmp/i1/
C> invalid socket path: tmp/i1//admin.sock
[supervisor:214288] no ipc message from child
[supervisor:214288] subprocess 214289 exited with code 1
```

Introduce a plugin system for picodata cluster.
Plugin system contains:
- `picoplugin` crate with plugin interfaces.
This crate exposes plugin interfaces for user implementation and API
that used by picodata to interact with plugin as with a code from dynamic library.
- Support for plugin work cycle in picodata instance work cycle.
Picodata instance interacts with running plugin by `PluginManager`
component.
Typically, plugins react to events that occur in instance or whole cluster.
- New lua API with plugin CRUD actions.
    - pico.create_plugin - load a new plugin into picodata cluster
    - pico.remove_plugin - remove plugin from picodata cluster
    - pico.update_plugin_config - update plugin service configuration
