Add support for partial granularity type

[hmstepanek]

Overview

This adds support for the concept of partial granularity distributed traces. There are 3 types:

• reduced
• essential
• compact

Add support for the following new configuration options:

distributed_tracing
   sampler
       adaptive_sampling_target
       full_granularity
           enabled
           remote_parent_sampled
           remote_parent_not_sampled
       partial_granularity
           enabled
           type
           remote_parent_sampled
           remote_parent_not_sampled

I just realized that simplify_distributed_tracing_sampler_granularity_settings() should either

1. be moved before the attribute_filter application, but right after apply_server_side_settings()
2. be removed all together and put the logic from that function in apply_server_side_settings() (maybe after the custom_insights_events.max_attribute_value override?)
