Rename --test-types to --parallel-test-types parameters

[potiuk]

The --test-type and --test-types parameters were very similar, but they have enough difference to differentiate them even more:

The --test-type is specifically to run single test and it might include not only the regular "test-types" but also allow for cross-selection of tests from different other types (for example --test-type Postgres will run tests for Postgres database and they might come from Providers, Others, CLI etc.

Where --test-types was generally foreseen to be able to split the tests into "sepearated" groups that could be run in parallel.

The parameters have different defaults and even different choice of test type that you could choose from (and --test-types is a space-separated one to make it easier to pass it around in CI, where rather than passing multiple (variable number) of parameters, it's easier to pass a single, even space-separated list of tests to run.

This change is good to show the difference between then parameters and to stress that they are really quite different, also it makes it easier to avoid confusion people might have especially that the name was easy to have typo in.

In a way (but different than in the original issue it Fixes: #30407

cc: @vandonr-amz - I made changes to breeze w/regards providers and I recalled the discussion from ##30407 and I found that it is really easy to just rename the --test-types parameter to avoid confusion . Here it is.

[vandonr-amz]

renaming the parameter is a breaking change though. Won't it break the CI here in github ?

Also, I agree that the rename is a step in the right direction to reduce confusion, but I still think it's weird to have parameters that are very similar but slightly different and incompatible in their use :/

I also corrected the Ci references. breeze is deliberately in Airflow repo so that they can evolve together and so we do not have to care about backwards compatibility. And this paran is mostly used in CI - most people even if run parallel tests they would run it with default value (all tests).

We have no expectations nor need about breeze being backwards compatible :)

I understand where you're coming from but i think it is really the matter of where you get 'common' part. We are reusing a lot of code under the hood to run the tests - including which test "type" is selected, and it's a bit arbitrary decision how to name parameters that internally might even consist of similar 'blocks' and use the same test types.

In this case i'd say separating it MORE is better because it removes confusion and typos

But of course if you would like to propose a PR changing it + i am happy to discuss seeing the code :)

Small quality of life improvement in breeze.
