* first pass

There's a lot happening here, so let's go through it:

* adding some helper routines in hadoop-functions to:
** convert strings to arrays if the array doesn't already exist
** add to arrays based upon a key to dedupe
* convert almost all internal users of HADOOP_OPTS and xyz_OPTS to use the array form
* update some pre-existing doc references
* add several unit tests
* rewrite existing unit tests to use the array form

To do:
* more/better docs
* figure out what to do about catalina?
* get HADOOP-13341 committed, since this code is several times larger without it
* more testing

> While we are mucking with all of the _OPTS variables, this is a good time to convert them to arrays so that filesystems with spaces in them can be used.
