Closes/Fixes #302

• added parameter builders for CREATE, ALTER, ADD, INCRBY, DECRBY
• added IGNORE option for set of commands
• added unit tests
• marked old commands(ones with multiple individual parameters) as obsolete and aiming to drop them with a major version release in future

thanks to @gerzse for comments and feedbacks on builder classes and method signatures
