authConfig form overlay: autocomplete="one-time-code"

[keul]

Depending on the kind of authorization provided in the authConfig, the browser native password manager (or browser's plugin ones) can be very noisy in case the value of the password field is intended to be a short lived.

In this case a autocomplete="one-time-code" should enhance the user experience: https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/autocomplete

As this is probably not a solution for all usecases, it should be probably enabled on demand, like another option in the authConfig section.

I wasn't aware of all these options for autocomplete, sounds great.
Happy to accept such a PR.

@m-mohr happy to work on this in next days.

Question about the implementation: do you want a "free" new autocomplete property in authConfig (so, if I put "foo" there it will use "foo" in the markup) or something more controlled?

[m-mohr]

To be compliant with #304, I think the authConfig should get something like:

generatorOptions: {
  autocomplete: "one-time-code"
}

Should one-time-code be the default? Would be fine with me, I think. And it can just be passed through, I think.

[keul]

yup, for me "one-time-code" is a good default
