Introduces a small, isolated interface for reading a JWT from a file path — the first piece of the upcoming Conjur JWT authentication path, split out on its own since nothing else in this PR depends on it yet.
identity.go mixed the shared client/token-cache plumbing with the CyberArk Identity username/password (UP) login flow. Move the UP-specific code into username_password.go so the shared plumbing stays easy to find once a second login mechanism (Conjur JWT) is added alongside it. No behavior change — pure extraction, plus unexporting ActionAnswer and exporting the mock's success credentials for other packages' tests.
The Service Discovery API returns several independently-hosted services; the authn-jwt exchange this PR series adds is served by secrets_manager, a different host from identity_administration. Add a SecretsManager field to Services and parse it, so callers have it available — nothing reads it yet, that lands in a later PR alongside the client that needs it.
Exchanges a projected ServiceAccount JWT (via jwtsource) for a Conjur access token through the authn-jwt endpoint, and authenticates requests with it as identity.RequestAuthenticator. Nothing wires this in yet — that's the next PR, once both this and the legacy identity client exist side by side. The identity returned for audit tagging is the token's own sub claim when it can be extracted, falling back to the configured service ID otherwise, so an unusual token shape degrades rather than fails the request.
Adds NewRequestAuthenticator, choosing between the new Conjur JWT exchange and the legacy CyberArk Identity username/password login based on which config is present — Conjur JWT takes priority when both are set. Conjur JWT requires service_id and resolves its base URL from the secrets_manager service discovered in the prior PR, not identity_administration; the two are different hosts. Switches keyfetch's client over to the new authenticator selection instead of constructing a username/password identity client directly, so JWKS fetching supports both authentication methods too.
NewCyberArk and the agent config schema were still legacy-username/password-only at the top level, even though the underlying authenticator selection (previous PR) already supports Conjur JWT. Thread service_id/account/jwt_source/jwt_file_path through cyberark.service_id in the agent config down to NewCyberArk, so the config file is the single place an operator chooses which authentication method to use. config.go's call site and client_cyberark.go's signature change together — splitting them across two PRs would leave one non-building at every commit in between.
Exposes config.cyberark's new Conjur JWT fields (serviceId, account, jwtSource) in values.yaml/values.schema.json, and documents per-cluster Conjur onboarding as a prerequisite in the chart README — the tenant administrator's own Conjur Cloud credentials, no admin credential needed at deploy time.
