Prepend NGSI-v1 to the v1 tests, NGSI-v2 to the v2 tests

[jason-fox]

Simple Grep rename of the descriptions of the NGSI v2 tests, to distinguish them from the NGSI-LD test suite

Also updated the NGSI-v1 test files which have equivalent tests to distinguish between v1, v2 and LD

I'm not sure of your PR philosophy here, given that this PR touches tests only should I:

a) Make minimal changes (as is)
b) Prettify the changed test files - to reduce the scope of #753
c) Update the tests to run using ES6 syntax - to reduce the scope of #831

Not sure but many of these tests are "parallel" to existing ones in NGSIv1 (maybe @dcalvoalonso could confirm, as he did great part of the implementation).

In that case, maybe it's a good idea to add a 'NGSI-v1 - prefix also in those ones, for the sake of completeness.

I'm not sure of your PR philosophy here, given that this PR touches tests only should I:

a) Make minimal changes (as is)
b) Prettify the changed test files - to reduce the scope of #753
c) Update the tests to run using ES6 syntax - to reduce the scope of #831

This case is different from #841 (comment) in the sense in this case the test files are not new but pre-existing.

In my opinion, the decision should depend on the impact on other people's ongoing works. In other words, are the test files you plan to change already being changed in some of the ongoing PRs we have in the repository (apart from yours and mine)?

are the test files you plan to change already being changed in some of the ongoing PRs

Since the update now touches both NGSI-v1 and NGSI-v2 the answer would be YES
I'd prefer just to complete the title changes for now.
