[ML] Outlier detection should only fetch docs that have the analyzed … (#44944) (#44959)
As data frame rows with missing values for analyzed fields are skipped,
we can be more efficient by including a query that only picks documents
that have values for all analyzed fields. Besides improving the number
of documents we go through, we also provide a more accurate measurement
of how many rows we need which reduces the memory requirements.

This also adds an integration test that runs outlier detection on data
with missing fields.
