      Description

      With MongoDB 4.2 the Index Name Length restriction was removed (SERVER-32959), however when running latest mongorestore while targeting a 4.2.x cluster the following error can still be thrown:

      2020-02-26T03:00:08.839+0000	Failed: xxx.yyy: error creating indexes for xxx.yyy: cannot restore index with namespace 'xxx.yyy.$meta.groupGeocode.coordinates_2dsphere_meta.groupTransactionDate_-1_meta.groupTimestamp_-1': namespace is too long (max size is 127 bytes)

      mongorestore should be testing the target cluster's fCV and if it's < 4.2 the string length test can still be applied.

      see https://github.com/mongodb/mongo-tools/blob/31aaebec00b2fa74c9900e07d1e980ce4e6495ee/mongorestore/metadata.go#L166-L170.
