adjust openQA test suite names (install_foo not server_foo)
    
    Summary:
    We named a bunch of the	tests 'server_foo' back	when we	were
    starting out and didn't	really know what we were doing.	They're
    all really installation	tests, not 'server' tests. I actually
    want to	start adding some Server tests now, so it seems	like a
    good time to fix that mess. This standardizes on 'install_' as
    a prefix for installation tests, converting all	the 'server_'
    tests and fixing up a couple of	odd cases to use 'install_'.
    
    Test Plan:
    Apply along with the matching commit for tools, do
    a full test run and report test, and make sure all tests run
    with the new names and correct ResTups are generated for wiki
    submission.
