request: ability to disable file creation

[hugomallet]

Hi,

I would like to disable the plugin depending on a variable (usually the stage).

For example:

custom: 
    exportOutputs: false

or

custom: 
    exportOutputs: 
        enabled: false
        include: ...

This could be used using stage option :

custom: 
    exportOutputsEnabled: 
        dev: true
    exportOutputs: 
        enabled: ${self:custom.exportOutputsEnabled.${opt:stage}, false}
        include: ...
