This test is removed as the s3n: URL could not be changed to s3a:, that would 
have defeated the goal of the test. Coverage for invalid, but still parseable 
URLs is still provided by the remaining test step checking 'file:///' URLs.

Done.

The credentials section is now completely removed (it can still be added 
manually if someone really needs it); dummy credentials required by the FE 
tests are supplied via environment variables. s3a: can take this form; s3n:, 
which can only understand the entries in core-site.xml has been removed from 
the codebase.

I had to remove a single test from AnalyzeStmtsTest.java so that s3n: could be 
completely removed; I left some notes there.
