------------------------------------------------------------------

On the second thought, we should not examine all DLLs in the folder.
* Scanning all assemblies in a folder is unsafe and slow
* User may want to load specific plugins only, or decide dynamically which ones should be loaded

So the proper way is to specify a list of {{IPluginProvider}} implementations via {{ICollection<Type> IgniteConfiguration.Plugins}}.
This requires one extra step from the user, but allows precise control.

> Define plugin API in .NET similar to Java API:
> * {{IgniteConfiguration.PluginConfigurations}}
> * {{CacheConfiguration.PluginConfigurations}}
> * {{IPluginProvider}}
> * {{ICachePluginProvider}}
> * {{IPluginContext}}
> * {{ICachePluginContext}}
> Should work like this:
> * Plugin author implements {{IPluginProvider}}
> * We discover plugins on Ignite start by examining all DLL files in the folder, load DLLs where {{IPluginProvider}} implementations are present, instantiate these implementations, and call {{IPluginProvider.Start(IPluginContext)}} method.
> * Plugin user can retrieve plugin via {{IIgnite.GetPlugin<T>(string name)}}, or via helper extension method provided by plugin author.
> This task does not include the possibility to interact with Java from the plugin code.
