tests: rework test parameters

there were 2 variants of calling getTestParameter:

    - parameter, description, default value
    - parameter, env value, default value, description, scope

While scope was never actually used and having 2 names for the same value led
to having 2 different entries in the cache file for the same configuration.

This commit removes the variants and simplifies tests parameters by only using
the first 3 parameter variant.

-The option exists to store parameters in a scoped means, allowing a
-test harness to a localise a parameter should the need arise. This
-allows a parameter of the same name to exist in a test harness
-specific scope, while not affecting the globally scoped parameter. The
-scoping identifier is the name of the test harness sans the trailing
-".t".  All cache searches first look to a scoped parameter before
-looking for the parameter at global scope. Thus for a test harness
-called "check_disk.t" requesting the parameter "mountpoint_valid", the
-cache is first searched for "check_disk"/"mountpoint_valid", if this
-fails, then a search is conducted for "mountpoint_valid".
