Add support one-time token value customization

[franticticktick]

It is necessary to add the ability to customize the generation of the one-time token value. Now it is:

String token = UUID.randomUUID().toString();

I think we could introduce a OneTimeTokenProvider interface with default implementation that uses UUID to generate one time tokens, I can prepare a draft PR.

Hi @evgeniycheban , thanks for the suggestion. We already have a DefaultGenerateOneTimeTokenRequestResolver. I am considering adding token value customization to this component. For example, setTokenValueFactory or something like that

[evgeniycheban]

Yes, that would make sense to add it to GenerateOneTimeTokenRequest, I think setTokenValueFactory may accept a Supplier<String> or maybe it is worth introducing a dedicated interface for that.

@franticticktick would you be able to submit a PR or I can take this one?
