Tempo Support - Rename to Tracing instead of Jaeger when applicable

[josunect]

This is a refactoring task to use Tracing instead of Jaeger for types and package names because there was included support for other than Jaeger trace providers (Tempo at the moment).

Please note, Tempo client reads the traces in OpenTelementry format and they are converted into Jaeger Traces, so in case of a Jaeger trace types the rename is not applicable.

Some examples:

• https://github.com/kiali/kiali/blob/master/business/jaeger.go
• https://github.com/kiali/kiali/blob/master/routing/routes.go#L1274 (At the moment Backstage does not use Jaeger, so it is not impacted. OSSMC should be updated).
• https://github.com/kiali/kiali/tree/master/frontend/src/components/JaegerIntegration
• https://github.com/kiali/kiali/blob/master/frontend/src/types/JaegerInfo.ts
