True when the evidence supports deploymentType: exactly one built-in
client redirected to the login (cloud or forgeops), or both clients
answered 400 (an AM that has neither built-in client: classic). False
when the host did not answer or answered something that is not
AM-shaped (404, 403, an HTML page, a redirect elsewhere, both clients
redirecting). An unreachable or mistyped host is inconclusive, not
classic.
'cloud' | 'forgeops' | 'classic'. 'classic' is also what an inconclusive
probe returns, for backward compatibility: check conclusive before
trusting it.
The raw per-client evidence the type was derived from.
Probe with the cloud built-in client (idmAdminClient).
Probe with the ForgeOps built-in client (idm-admin-ui).
Result of the anonymous deployment-type probe (see
Authenticate.probeDeploymentType()).
