Changes in this update
* **Enhancements**
* Updated MediaPlayer to solve stability issues
* All capability agents were refined to work with the updated MediaPlayer
* Added the TemplateRuntime capability agent
* Added the SpeakerManager capability agent
* Added a configuration option ("sampleApp":"endpoint") that allows the endpoint that SampleApp connects to to be specified without changing code or rebuilding
* Added very verbose capture of libcurl debug information
* Added an observer interface to observer audio state changes from AudioPlayer
* Added support for StreamMetadataExtracted Event. Stream tags found in the stream are represented in JSON and sent to AVS
* Added to the SampleApp a simple GuiRenderer as an observer to the TemplateRuntime Capability Agent
* Moved shared libcurl functionality to AVSCommon/Utils
* Added a CMake option to exclude tests from the "make all" build. Use "cmake <absolute-path-to-source>
-DACSDK_EXCLUDE_TEST_FROM_ALL=ON" to enable it. When this option is enabled "make unit" and "make integration" still could be used to build and run the tests
* **Bug fixes**:
* Previously scheduled alerts now play following a restart
* General stability fixes
* Bug fix for CertifiedSender blocking forever if the network goes down while it's trying to send a message to AVS
* Fixes for known issue of Alerts integration tests fail: AlertsTest.UserLongUnrelatedBargeInOnActiveTimer and AlertsTest.handleOneTimerWithVocalStop
* Attempting to end a tap-to-talk interaction with the tap-to-talk button wouldn't work
* SharedDataStream could encounter a race condition due to a combination of a blocking Reader and a Writer closing before writing any data
* Bug-fix for the ordering of notifications within alerts scheduling. This fixes the issue where a local-stop on an alert would also stop a subsequent alert if it were to begin without delay
* **Known Issues**
* Capability agent for Notifications is not included in this release
* Inconsistent playback behavior when resuming content ("Alexa, pause." / "Alexa, resume."). Specifically, handling playback offsets, which causes the content to play from the start. This behavior is also occasionally seen with "Next" /
"Previous".
* `ACL`'s asynchronous receipt of audio attachments may manage resources poorly in scenarios where attachments are received but not consumed.
