[rid-prober] migrate prober logic entirely to uss_qualifier scenarios, then remove prober

[Shastick]

We (progressively) want to retire the current prober entirely.

Before doing so, we need to ensure that everything it tests is also being tested by uss_qualifier scenarios.

We will do so step-wise, starting with the part of the prober that tests the remote ID part of the standards.

Gap Analysis

The following gap analysis is based on both the older InterUSS Backlog as well as a manual check of the prober files and their corresponding qualifier scenarios for RID.

In summary, the qualifier covers at least what the prober is covering with respect to both Remote ID standards v1 and v2.

prober file	qualifier scenarios	comments	migrated
v1/test_isa_expiry.py	ISAExpiry		✅
v2/test_isa_expiry.py	ISAExpiry		✅
v1/test_isa_simple.py	ISASimple		✅
v2/test_isa_simple.py	ISASimple		✅
v1/test_isa_simple_heavy_traffic_concurrent.py	HeavyTrafficConcurrent	qualifier covers both v1+v2	✅

v2/test_subscription_isa_interactions.py	ISASubscriptionInteractions		✅
v1/test_subscription_isa_slightly_overlapping.py	ISASubscriptionInteractions	qualifier scenario covers both v1+v2, and checks for subscriptions slightly overlapping the ISA	✅
v1/test_subscription_simple.py	SubscriptionSimple		✅
v2/test_subscription_simple.py	SubscriptionSimple		✅
v1/test_subscription_validation.py	SubscriptionValidation		✅
v2/test_subscription_validation.py	SubscriptionValidation		✅
v1/test_token_validation.py	TokenValidation		✅
v2/test_token_validation.py	TokenValidation		✅

It should be noted that until interuss/dss#1045 is merged on the DSS repo, the DSS CI will not be running the qualifier as part of the automated tests.

interuss/dss#1066 adds mentions and pointers to the qualifier to the DSS doc
