      Description

      A DNS name is fully qualified if the name ends with a dot.

      We expected that a fully qualified DNS name would work with mongo-go-driver, in the same way that an unqualified name would:

      mongodb+srv://internal.mongos-main.svc.svc.our.company.tld./?valid=opts
      

      Unfortunately, we get an error in this case:

      error parsing uri: Domain suffix from SRV record not matched input domain
      

      The SRV record is indeed valid:

      ; <<>> DiG 9.10.6 <<>> SRV _mongodb._tcp.internal.mongos-main.svc.our.company.tld.
      ;; global options: +cmd
      ;; Got answer:

      _mongodb._tcp.internal.mongos-main.svc.our.company.tld. 5 IN SRV 0 50 27017 internal-796c7f96b7-k488c.internal.mongos-main.svc.our.company.tld.
       
      ;; ADDITIONAL SECTION:
      internal-796c7f96b7-kdjqf.internal.mongos-main.svc.our.company.tld. 5 IN A 10.1.1.148
      internal-796c7f96b7-k488c.internal.mongos-main.svc.our.company.tld. 5 IN A 10.1.1.83
      

      And the driver does otherwise work if we drop the trailing dot.
