Update opentelemetry.io cookbook with common view scenarios

[aabmass]

https://opentelemetry.io/docs/instrumentation/python/cookbook/

Some possible common scenarios:

• turn off a metric
• turn off all metrics from a given instrumentation
• turn default views off and require explicitly turning individual instruments "on" (basically this)

We have few examples created already here https://github.com/open-telemetry/opentelemetry-python/tree/main/docs/examples/metrics/views

Some of the requirements from the original description are already covered so please don't duplicate the same work.

hi @srikanthccv i would like to work on this scenario. turn default views off and require explicitly turning individual instruments "on" should i go ahead or you have another suggestion for me

[srikanthccv]

Sure, go ahead. I don't think we have covered that scenario yet.
