[core][core-http] createPipelineFromOptions needs a way to skip retry policies

[xirzec]

Currently there is no good way to disable the built-in retry logic when using createPipelineFromOptions:

azure-sdk-for-js/sdk/core/core-http/lib/serviceClient.ts

Line 687 in f2940c3

throttlingRetryPolicy(),

This makes it tricky for Storage to apply its custom retry policies. For now we are relying on the fact that these policies are always the last three, but in the future it would be nice to have some way to identify these policies in the array (so they can be removed or inserted before/after)

We should solve this problem of libraries subclassing ServiceClient and needing custom pipelines before exposing this machinery to users.

This can be easily done with core-rest-pipeline, so new service clients built on top will be able to configure it
