Before this change, serverStatus() accepts an argument which excludes top-level sections, eg `

`. this change allows detailed exclusion of metrics, eg `{metrics: {query: {multiPlanner: {histograms: false}}}}`. both individual fields/metrics and objects/branches can be excluded

Description of Linked Ticket

Motivated by work on SERVER-63642, we would like to exclude some serverStatus metrics from FTDC collection. This is not possible with the current serverStatus command which only allows excluding top-level sections/keys from the output. The result of implementing this task is that we would be able to exclude arbitrarily nested elements from the metrics output.
