Possibility to vote for all independent of the number of options

[arashgmn]

Summary

It would be nice to have a multiple-response poll which allows users to vote for all options even if the number of options in the poll is updated. Currently, if a multi-response poll is created via --vote=X (with X being the number of options), once a new option is added, a user who has spent all of their X quota, can never vote for the new option.

Describe alternatives you've considered

I'm a mere user with no experience in developing Mattermoist plugins. So, I have not tried anything personally, but these two different approaches come to my mind:

1. Extend the --vote=X feature to increase the maximum number of votes X by one as options are added (not recommended because it may not be the intended purpose),
2. Introduce a new boolean argument (something like --vole-all) that separates the --vote=X functionality from the vote for all feature.

Additional context

#256 is relevant, but a different feature.

Could we use --vote=0 here as a special case that means: a user has an unlimited amount of votes?

[arashgmn]

AFAK --vote doesn't accept zero as an argument. So, assigning 0 to unlimited votes wouldn't clash with its functionality, and in principle a good idea.

I want this too.

Definitely needed feature. Any update on this?
