------------------------------------------------------------------
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.
We can combine this with {{IgniteConfiguration.PluginConfigurations}}, so that
plugin author provides {{IPluginConfiguration}} implementation with mandatory
{{PluginProviderFactory}} property.

> Define plugin API in .NET

> Key: IGNITE-4441
> URL: https://issues.apache.org/jira/browse/IGNITE-4441
> Project: Ignite
> Issue Type: Sub-task
> Components: platforms
> Reporter: Pavel Tupitsyn
> Assignee: Pavel Tupitsyn
> Labels: .NET
> Fix For: 2.0
>
>
> 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.
