Document how hotfix releases differ from normal releases

Suggestion:

1. No waiting for buy-in
2. No waiting 48 hours after enough positive votes, add to email text that voting is closed earlier because of hotfix

In theory, I believe only security fixes are supposed to be allowed to have expedited releases, but the Apache guidelines aren't super explicit about this.

For the record, the voting guidelines also say votes should run for at least 72 hours. (Although the release process document emphasizes "should" rather than "must").

All releases must have a minimum of three +1 votes, and there's some requirements as to what the PMC members must do before voting.

To clarify, I'm not personally opposed to expediting an urgent bugfix release like this one. It makes sense, and it's the right thing to do. I'm just concerned that we could run into issues with the board for failure to adhere to guidelines (which has happened in the past)

All I wrote here is of course a restriction/change to what is already documented in https://github.com/apache/cordova-coho/blob/master/docs/release-voting.md and https://github.com/apache/cordova-coho/blob/master/docs/tools-release-process.md (which needs to be extracted into its own file as well probably).

We should definitely check with Apache guidelines and whoever decides there what is possible and what is not. We just made a judgement call right now, and I wanted to start the formalisation process of that because I couldn't find anything in Cordova land.
