Allow to disable telemetry exporters in ci-framework jobs

There are certain cases where we want to disable specific telemetry
exporters in ci-framework jobs, i.e. watcher jobs where the required
metrics to test watcher features are injected into prometheus directly.

This patch is adding a variable cifmw_edpm_telemetry_enabled_exporters
which can contain the list of desired exporters in the telemetry enabled
deployment.
