Add Machine Learning filter APIs and detector custom rules (#3632)

* Add ML filters APIs

This commit adds the Put, Get, Update and Delete filters APIs,
required for working with ML detector custom rules

* Add ML detector custom rules

This commit adds custom rules to machine learning
detectors. The name of types used closely follows those
used in Elasticsearch source.

* Remove "integer" from API generator

"integer" is no longer a type used within the spec
