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

Also here we refactor all the places where we checked command line
parameters, because now PicodataConfig is the main source of this
information.

New tarantool options 'memtx_memory' and 'log' can be configured via
picodata cli

1. Hide `picodata tarantool` from help
2. Mark `picodata run -i` option deprecated
3. Renew `picodata help connect`
4. Renew `picodata help admin`

Also print new greeting and help

1. Add a new option picodata run --shredding to enable shredding upon xlog_remove_file_impl.
2. For test purposes additionally use the inject_errors feature to keep files after shred operation
and allow the test code to look inside and make sure that content was really shredded.

Note: this changes return values from all .proc_* stored procedures,
making them more usable, but completely breaking the compatibility with
older versions.

Closes #500
