GEOMESA-120 Extract Temporal Filters

* We now extract the temporal range to cover from the applicable temporal filters.
* Since FilterToAccumulo is no longer used, it has been deleted.
  (This required tweaking one unit test.  Additional clean-up was involved.)
* Added 'pendingUntilFixed' unit tests to the QueryStrategyDeciderTest to reflect further work.
GEOMESA 320, use apache commons csv

* replaced usage of javacsv with 1.0 release of apache commons csv in geomesa-tools
* updated test to ensure wkt still works with commons csv
* updated pom
GEOMESA-330 Avro SimpleFeature's getProperty should return a Property even when the value is null
