Description

When passing arguments to schematics as options, I would like to be able to pass a dash-case option (i.e. ---dry-run) and get the camelCase equivalent (i.e. dryRun) in the options passed to my schematic.

Currently, if I pass the option option-one as a dash-case argument...

schematics my-collection:my-schematic --option-one=test

The factory function will receive the following options object...

{
    "option-one": "test"
}

Furthermore, if I were to pass both the dash-case and camelCase equivalent of the same argument like so...

schematics my-collection:my-schematic --option-one=test1 --optionOne=test2

The factory function will receive the following options object...

{
    "option-one": "test1",
    "optionOne": "test2"
}

This is not only very confusing but also inconsistent with the base schematics options such as --dry-run. Meaning that the following two commands are analogous...

schematics my-collection:my-schematic --dry-run=true
schematics my-collection:my-schematic --dryRun=true

Thereby treating dry-run as dryRun. I don't see a great use case for allowing two arguments of different cases to coexist.

Describe the solution you'd like

Option 1

Coerce all options argument to camelCase.

Option 2

Smart case corecursion of all options argument based on options schema.

Describe alternatives you've considered

Checking for both dash-case and camelCase options and resolving each option manually based on expected options schema.
