sample POST fails on pipeline publish if user & project IDs not explicitly set

[Eoghan Glynn]

If the user and project IDs are not explicitly set, POSTing a sample to the v2 meters API fails with asynchronously when the sample is published[1]

These IDs should default to the current auth context.

    Default to ctx user/project ID in sample POST API

    Fixes bug #1202143

    Avoid RPC failure when project and user IDs not explicitly
