      Description

      Starting from this push in 10.10

          MDEV-27105 --ssl option set as default for mariadb CLI
          
          but without server cert verification
      

      some tests take many times longer, and almost inevitably fail with timeout. E.g. rocksdb.concurrent_alter fails on nearly every build/builder in buildbot, while before the change it was only taking a few seconds.

      On my machine the ratio is not as big, but still very visible (it's the command that the test runs inside):

      $ time $MYSQL_SLAP  --silent --delimiter=";" --query="select * from a1 where a=1" --concurrency=16 --iterations=1000
       
      real	0m10.935s
      user	0m9.951s
      sys	0m3.147s
       
      $ time $MYSQL_SLAP --skip-ssl --silent --delimiter=";" --query="select * from a1 where a=1" --concurrency=16 --iterations=1000
       
      real	0m0.841s
      user	0m0.457s
      sys	0m2.026s
      

      Probably there are other affected tests, the rocksdb is only most visible because it actually fails.

      we probably need to change MTR default config to turn off SSL for mysqlslap, but first it needs to be confirmed that such a difference in default client performance is expected.
