Bug Report

maxBitrate in VIDEO_STREAMING capability is read in wrong unit

Reproduction Steps

1. Start video streaming SDL app and make sure RegisterAppInterface get succeeded with video capable HU.
2. send GetSystemCapability {"systemCapabilityType":"VIDEO_STREAMING"}
3. make sure getting GetSystemCapability response, something like:
   "systemCapability" : {
   "systemCapabilityType" : "VIDEO_STREAMING",
   "videoStreamingCapability" : {
   "hapticSpatialDataSupported" : false,
   "maxBitrate" : 10000,
   "preferredResolution" : {
   "resolutionHeight" : 416,
   "resolutionWidth" : 800
   },
   "supportedFormats" : [
   {
   "codec" : "H264",
   "protocol" : "RTP"
   },
   {
   "codec" : "H264",
   "protocol" : "RAW"
   }
   ]
   }
   }
4. startVideoStreaming with given VideoStreamingParams.

Expected Behavior

Video streaming works in appropriate bitrate.

Observed Behavior

Video streaming on HU looks very poor quality.

OS & Version Information

• Android Version: Android 7.0 (Samsung Galaxy S8)
• SDL Android Version: commit daaac59 from develop branch
• Testing Against: running on our video-capable dev-board

Test Case, Sample Code, and / or Example App

I will create PR later, but in short, it is a bug in VideoStreamingParameters class.
According to hmi_integration_guideline, maxBitrate is described as "The maximum bitrate of video stream that is supported, in kbps.", but the code treats it as bps.
