Custom Cloudwatch metric

[SanjayGhanagiri]

Add initial implementation of CloudWatch Metrics Collector

This commit introduces the CloudWatch Metrics Collector, including the necessary configuration files and scripts to build and start the collector. The collector is designed to fetch metrics from AWS CloudWatch and process them using OpenTelemetry. Key files added include:

• build.sh and buildAndStartCollector.sh for building and starting the collector.
• builder-config.yaml and config-metrics.yaml for configuration settings.
• The main collector code and necessary dependencies for AWS integration.

This setup enables users to collect and export metrics from AWS CloudWatch seamlessly.
