use bash arrays in test/get*HLT.sh scripts

Update of the scripts

HLTrigger/Configuration/test/getHLT.sh , and
HLTrigger/Configuration/test/getFrozenHLT.sh

to use an associative array to specify which
HLT configurations should be downloaded from ConfDB.

This allows for more flexibility for non-standard use cases
(e.g. having to specify different version numbers for different subtables).
In getFrozenHLT.sh , this change also avoids having
to specify the list of configurations in a separate string
(which was named TABLES prior to this commit):
now, it is sufficient to add a new configuration to the associative array.

The downside of using associative arrays is that
the configurations are not downloaded anymore in a specific order,
but said order is (and should be) unimportant in this context.
