Currently, the only autodetection logic that findspark has is to check
where homebrew installs Spark on OSX. I think that for pyspark this is overly
specific and brittle, and can lead to confusion if the user wanted to use
pyspark with a different version than the one installed by homebrew. Having the
user set SPARK_HOME themself makes the process unambiguous.
