BREAKING CHANGE: "name" index in the _pico_index has changed:
previously it guarantees uniqueness for a pair of (space_id,
index_name). Now index name must be unique among the cluster.
So, all the global indexes for _pico tables were renamed.

BREAKING CHANGE: _pico_index structure has changed.

The reason for refactoring is the request for the cluster wide
indexes with all possible options. The old structure didn't allow
us to support them all.

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

We don't expect users to be changing those too often.

This MR introduces many more patches needed to fix almost all known
issues with gamayn and svace (with exception of libdecnumber).

Additionally it does some improvements to workflow, now helper script
has `restore` command to clear dirty state when patches were applied to
simplify testing.

For places where asserts where needed they're extended with panic calls
because for static analyzer we need to sometimes prove that condition
holds even in release build where usual asserts are disabled.

Also this patch bumps webui repo to accomodate fixes made there.
