Provide defaults for ConfigOption's constructor
It's handy to be able to easily make a blank ConfigOption instance. As such
providing defaults for everything except its name.

(Default: 1 GByte)\n\nWith this option, and in other options that take arguments in bytes, KBytes, and so on, other formats are also supported. Notably, "KBytes" can also be written as "kilobytes" or "kb"; "MBytes" can be written as "megabytes" or "MB"; "kbits" can be written as "kilobits"; and so forth. Tor also accepts "byte" and "bit" in the singular. The prefixes "tera" and "T" are also recognized. If no units are given, we default to bytes.
