869 Create ranger_solr_log_dir

[PACordonnier]

Which issue(s) this PR fixes

Fixes #869

Additional comments

There was no ranger_solr_log_dir variable set. Ranger solr logs were located in ranger_log_dir along with ranger admin/kms/usersync... It could be better and it creates issue since ranger's setup.sh set permissions on this dir and create permission issue for ranger.

Note that to add this feature on a running cluster, one must add ranger_solr_log_file in tdp_vars/tdp_cluster
