This will be a start to generalize all argument validation errors. As currently we throw ARG/OPT, OUT_OF_RANGE, and other more specific errors. The OPT errors didn't bring much to the errors as it's just another variant of ARG error which is sometimes more confusing (some of our code used OPT errors to denote just argument validation errors presumably because of similarity of OPT to 'option' and not 'options-object') and they don't specify the name of the options object where the invalid value is located. Much better approach would be to just specify path to the invalid value in the name of the value as it is done in this PR (i.e. 'options.format', 'options.publicKey.type' etc) Also since this decreases a variety of errors we have it'd be easier to reuse validation code across the codebase.
