Fix/c sharp operations member name casing

[mariusmuntean]

Description

Added support for the new configuration option memberNameConvention to the c-sharp-operations plugin. Now both C# plugins can generate C# code with standard member casing.
The default is still camel case, to avoid generating code that breaks user's existing code base.
