OTEP #168 spawned a very long comment thread here:
#168 (comment)

This PR is an update to the text of OTEP 170 with more detail on composing probability and non-probability samplers.

This changes the name used in OTEP 170 for "head trace sampling" to "parent trace sampling" to better fit the model where spans can make independent decisions.

This uses "head trace sampling" only to describe sampling decisions being made at the root of the trace.

This changes the field returned by the Sampler to be named log_adjusted_count since it applies to both the new span and the new child context, not the "head".
