Fixes broken TracerFactory

[idealerror]

What was changed

• Updated open-telemetry composer versions to 1.0 as 0.0.17 no longer exists
• Updated TracerFactory to use latest naming convention for OpenTelemetry Signals
• Fixed TracerFactory merge() functions that don't exist

Why?

Open telemetry package versions caused docker container build to fail
TracerFactory bugs caused PHP Fatal Errors
