cli/command: disable retries for the OTLP exporters

The CLI flushes traces and metrics at exit with a 50ms timeout
(ExportTimeout). The OTLP gRPC exporters were created with the default
retry policy, so when the endpoint refuses the connection the export
keeps backing off until the timeout expires instead of returning.

This happens on every command when the current context points at a
unix socket that has no listener, for example Docker Desktop's context
while Desktop is not running, which leaves its analytics socket file
behind. A retry cannot complete within 50ms anyway, so turn retries off.
