Configuration class for `PipelineTask`
This Configuration class functions in largely the same manner as any other
derived from `lsst.pex.config.Config`. The only difference is in how it is
declared. `PipelineTaskConfig` children need to be declared with a
pipelineConnections argument. This argument should specify a child class of
`PipelineTaskConnections`. During the declaration of a `PipelineTaskConfig`
a config class is created with information from the supplied connections
class to allow configuration of the connections class. This dynamically
created config class is then attached to the `PipelineTaskConfig` via a
`~lsst.pex.config.ConfigField` with the attribute name `connections`.
