Add an optional OpenTelemetry Collector in front of Jaeger

[kolomiets]

For certain OTEL distributions that do not provide Jaeger Exporter (AWS Distro for OpenTelemetry) it's difficult to utilize Jaeger. In order to address that, a simple instance of OpenTelemetry Collector pre-configured to receive traces via OTLP and export them to Jaeger may be deployed.

Provide the following parameters to the entry templates:

• OpenTelemetryCollector (Yes/No)
• OpenTelemetryCollectorVersion (default: 0.50.0)

If deployed, the main Jaeger load balancer will expose OTLP receiver endpoint on normal 4317 port.
