This CL wires everything up and enables actual setting of the max bitrate encoding parameter on the video RTP sender. The following changes were made * Add maxbitrate property to the settings model and settings store. Make sure to store and read the maxbitrate from storage (to persist between app launches and make testing easier) * Fix setup of encoding parameters for the rtp sender as previous timing was not right. * Fix header of RTCRtpSender to expose needed parameter BUG=webrtc:6654 Review-Url: https://codereview.webrtc.org/2492693003 Cr-Commit-Position: refs/heads/master@{#15120}
