Remove equinix otel dependency

[chrisdoherty4]

The Equinix Otel library tries to be too magic and make telemetry instrumentation "just work" by configuring a set of environment variables. These environment variables often go undocumented and are hard to keep track of.

We should preference clear configurability over cleverness, hence we should remove the Equinix otel instrumentation in favor of explicit otel instrumentation.
