An ability to set action callback without Aura context wrapper - $A.getCallback()

[ruslan-kurchenko]

By default, then(), catch() and finally() function wraps callback function with $A.getCallback().
Lax should provide an ability to avoid that.
There are can be situations where it is redundant, for example when callback doesn't change any component attribute and doesn't manipulate DOM.

An example of usage:

    component.lax.enqueue('c.actionName')
      .then(() => {
        // custom logic
      }, false)

API:

• then(callback, isAuraContext)
• catch(callback, isAuraContext)
• finally(callback, isAuraContext)

isAuraContext - is true by default
