Expose easing animation time in QCircularProgress and QLinearProgress

[rfox12]

I found that I have "jumpy" progress because my app updates every second or so. The easing animation on progress is a nice feature of Quasar, but to make it look really polished, it would be nice if the animation time was exposed as a variable that the developer could set. In my case I found that if I changed the default 0.6s ease to 1s ease that the result looked really nice.

<circle 
  class="q-circular-progress__circle text-secondary" 
  fill="transparent" 
  ...
  style="transition: stroke-dashoffset 1s ease 0s, stroke 1s ease 0s;">
</circle>

Not sure what the proposed attribute should be called... maybe "easeInterval"?

<q-circular-progress ease-interval="1s" value=...etc>

New prop (animation-speed) for QLinearProgress and QCircularProgress will be available in Quasar v2.2.5.
