refactor: prefix all manifest data classes with Manifest

Avoids name collisions with same-named runtime/plugin classes
(e.g. manifest AgentProvider vs plugin AgentProvider ABC,
manifest EgressRoute vs runtime EgressRoute). Renamed:

  AgentProvider        → ManifestAgentProvider   (manifest_agent.py)
  Agent                → ManifestAgent            (manifest_agent.py)
  EgressRoute          → ManifestEgressRoute      (manifest_egress.py)
  PathMatch            → ManifestPathMatch        (manifest_egress.py)
  HeaderMatch          → ManifestHeaderMatch      (manifest_egress.py)
  MatchEntry           → ManifestMatchEntry       (manifest_egress.py)
  EgressConfig         → ManifestEgressConfig     (manifest_egress.py)
  Bottle               → ManifestBottle           (manifest.py)
  ProvisionedKeyConfig → ManifestProvisionedKeyConfig (manifest_git.py)
  GitEntry             → ManifestGitEntry         (manifest_git.py)
  GitUser              → ManifestGitUser          (manifest_git.py)
