Cloudwatch integration demo

[disa6302]

Issue #, if available:

What was changed?

• Added a new demo that shows integration with cloudwatch metrics and logs, pushing RTP metrics and some end to end stats with mock frames, along with demonstrating some metrics with storage. The SDK depends on AWS SDK CPP and builds the monitoring and logs component if run with -DENABLE_AWS_SDK_INTEG=ON. The demo project uses a config file based mechanism to set the different options in our C SDK. The demo uses the same underlying common.c and other common wrappers that our samples use today

• Rearranged Common.c into different files to add more clarity to the basic building blocks of the existing samples

• Created a new MetricsHandling object that handles RTP stats calculation. ICE stats are still out of this and treated separately to avoid potential breaking in customer application.

Why was it changed?

• Setting up this demo would help in testing out our core samples library with different run time and calculate performance metrics
• It also helps customers get a head start if they are interested in integration with cloudwatch.

How was it changed?

• Included a new cloudwatch-integ folder that has the heart of the logic
• Included a new cmake arg to build this only if the arg is set
• Created config files for different job configurations. Default is set and new ones can also be created for new configs in the future. Config files are cleaner since it lays out the available knobs clearly to run the demo. Config file paths can be passed via -DCW_CONFIG_HEADER option
• Added MetricsHandling (StatsCtx) object that handles RTP stats
• Cleaned up Common.c to be split into multiple source files to clearly define purpose. No code changed here - only rearranging.
• Included new options in pSampleConfiguration that was required for this demo and will also be useful for existing samples
• Added a new API setUpCredentialProvider to set up IoT/long term credential provider. This is a mandatory requirement if using the samples provided with the next release - this change was made since this set up was masked behind a #ifdef block which would require sample modification, this is not conducive for the demo specifically if these decisions are taken based on a config file or even environment variable.

What testing was done for the changes?

• Running the demo in a CI set up to confirm metrics and logs are emitted to cloudwatch
• Tested the existing samples to confirm it is not broken.
