Add taglibs and internal checks to verify for enabled features

[ppazos]

Some features should be enabled or disabled depending on the cloud plan.

We need to be able to check if a feature is enabled for the current user, org and account on the web console, and display or hide the feature accordingly.

A second check level should be done in the correspondent controllers and services where the logic of that feature is defined. Because some features can be accessed from the API.

We also have an option for features to appear or disappear using plugins, but this is not for cloud but to deploy on clients with specific licenses https://stackoverflow.com/questions/56173292/extending-the-gui-from-plugins-in-grails-3/56173405#56173405
