MM 7971 dockerhost -> localhost && docker -> docker-compose (#10872)

* replace dockerhost with localhost

* remove uneeded setup-max build step (no more dockerhost)

* changes as recommended by @cpanato

* make clean-docker with docker-compose

* added ports to docker-compose.yml (needed for osx).   ignore error for ldapadd (when already exists)

* add clean-old-docker to legacy.mk

* docker-compose stop instead of down for `make stop-docker`
