Add default split points for reserved sections of the metadata table

**Is your feature request related to a problem? Please describe.**
As part of the init process, accumulo should add split points to the metadata table for the different sections (sserv, del, prob,blip, etc) so that they are initially contained within their own tablet files.

This will help with data organization.

Start by locating the initialization path that creates the metadata table and review how its tablets and split points are configured. Identify the reserved sections named in the issue, then verify that initialization assigns default split points so each section is initially contained in its own tablet file.
