fix: Use standard env variables for opentelemtry (#2194)

Browse Source 
Opentelemetry defines standard variables which are supported by multiple observability platforms.

[1] https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/sdk-environment-variables.md
[2] https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/protocol/exporter.md

By defining support for standard env vars, Fission open telemetry support can be leveraged with different
platforms such as NewRelic, SigNoz, DataDog etc.
