Remove LinearColorBar and replace uses with ProgressBar.

We never actually needed it, since progress bar can do
everything we want it to. Renamed data_usage_progress to
color_bar_progress to reflect its more generic state.

Updated color_bar_progress to use proper values.
Since we can't seem to use private attrs in settings,
use the dimen/color values that are customizable.

Updated usages to use regular ProgressBar APIs.
