.NET: Thin 3.0: Release procedure

Implement release procedure:

• Bump versions
• Update CSPROJ with package info properties (icon, description, license, etc)
• Build binaries
  • dotnet publish Apache.Ignite --configuration Release --output release/bin
• Build NuGet packages
  • dotnet pack Apache.Ignite --configuration Release --include-source --output release/nupkg
• Publish NuGet packages (manual step for now?)
