Added the Output "cluster_members" for the resource "aws_docdb_cluster".

This looks good to me if @kevcube is in favor as well. I believe this module creates one cluster so one() or flatten() is y'all's preference

[kevcube]

LGTM but @Faris96Hub I updated your PR title to feature instead of fix 😄

@RoseSecurity I'm the last committer here for a formatting fix so my approval doesn't count, can you approve?

@RoseSecurity any reasing for this not being included in 0.27?

as far as i can see the 0.26.2 should be the latest version. but tf registry shows 0.27 which does not include these changes

@schealex something got seriously messed up with our semver calculations, but these changes ARE included in the published v0.26.2, (which is published more recently than 0.27.0

so to use them today just reference 0.26.2.
