Consistent naming of interfaces and their implementations

[heiko-holz]

Currently, the project inconsistently uses the I prefix in interfaces.

E.g., public interface IGenericAction and public interface CommandExecutor.

We should adhere to a naming convention.

In this ticket, a naming convention for interfaces should be established and the existing interfaces and implementations should be refactored accordingly.

Things to consider

• naming of the interfaces
  • use the I prefix or not?
• naming of the implementations
  • when to use the Impl suffix in the implementations?
