Support serde serialization and deserialization

This commit adds serialization and deserialization support for the Verbosity type. The verbosity is serialized using the log::LevelFilter enum that represents the equivalent number of verbose and quiet flags. The serialized value is the uppercase variant of the enum variant. Deserialing is case-insensitive. Fixes: clap-rs#88
