The initial sync progress information in replSetGetStatus can grow very quickly since it reports information for every collection of every database. Currently we only have a boolean for whether or not we show the initial sync progress information, but it would be good to add an extra "condensed" level that only shows database granularity statistics with counts for how many collections have been cloned rather than details on each one.

As part of this improvement, it would be good to remove some of the duplicated namespaces that are shown. Currently the keys for each database are the database name, which is also included in the databases's statistics. A similar duplication occurs for collections.
