Add an alternative to action aware required param

[mourad-ifeelgoods]

Feature

In some use cases, we want a param to required depending of the action. we could use action aware params (see https://github.com/Apipie/apipie-rails#action-aware-params), but how to handle parameters optional on creation but required on update ?

A possible solution is to pass a list of actions for which to parameter is required (See examples below)

Make a param required for all actions

param :name, String, required true

Make a param required only for update action

param :name, String, required :update

Make a param required only for update and create actions

param :name, String, required [:update, :create ]

Note
Beware that the required param may still be overridden by action aware param if specified

Nice, thanks! Sorry for the delay, I was a bit late with the PRs lately.
