Refactor in BitrateController module.
 - Move condition of 0 bps as max meaning 1gbps from SendSideBandwidthEstimation to BitrateController.
 - Remove condition on bitrate=0 meaning bandwidth estimation off as that could only happen when no observers existed
   and in which case the estimation would be ignored.
 - Add MaybeTriggerOnNetworkChanged which only runs rate allocation if any of the dependent variables has changed
   thus allowing to remove many of the bool returns that try to indicate if the estimation has changed which would not
   be aware if the observers have changed.
 - SendSideBandwidthEstimation now has a UpdateBitrate and has clear code paths to which calls update bitrate.
 - Changes in enforce_min_bitrate so the 10kbps min is set from the BitrateController and not from the outside this keep valid as observers are changed.
