Add Application Signals runtime metrics

[bjrara]

Feature request

Add runtime metrics collection into Application Signals.

Description of changes:

1. Add JMX metrics template.
   1. The JMX template is taken from https://github.com/aws-observability/aws-otel-java-instrumentation/pull/817. The template is updated with bug fixes and added with additional CPU metrics. The author of the original PR is notified with the changes.
2. Introduce CloudWatchTemporalitySelector to set temporality of Application Signals exporter to alwaysDelta.
3. Add ScopeBasedPeriodicMetricReader to copy metrics from io.opentelemetry.jmx instrumentation scope to Application Signals exporter.
4. Set aws.local.service into resource attributes.
