Commit e7cd1f6cfab4d8448ad4ebd834727c83f23f4899 in kudu's branch

[docker] KUDU-3307: allow using multiple directories
Previously, the Docker entrypoint would by default use a single root
directory, suffixed with either 'master' or 'tserver'. This makes it a
poor fit for production systems that may want to use Docker, since most
reasonable deployments use multple data directories, and don't colocate
WALs and data.
This patch adds a couple of environment variables to the entrypoint,
FS_WAL_DIR and FS_DATA_DIRS, that map directly to the --fs_wal_dir and
--fs_data_dirs gflags that Kudu masters and tservers know and love.
To maintain compatibility with existing guides, the existing single-root
DATA_DIR remains, but the new environment variables, if set, take
precedence.

> Current docker entry point script takes environment variable {{DATA_DIR}}.
> However it's expected to be a single directory and that's supplied as
> {{-fs_wal_dir}} and not as one would expect {{-fs_data_dirs}}.

> We need to make updates to the entry script to be able to supply separate
> configuration for data directories. Need to ensure these directories are
> either created in the script or possibly within kudu server.
