Title:
  TLS handshake is fatal, not transient - hence not retried

Status in apt package in Ubuntu:
  Fix Released
Status in apt source package in Hirsute:
  Fix Committed

Bug description:
  [Impact]
  TLS handshakes are reported as fatal errors rather than transient errors like other connection errors on unencrypted connections. This seems wrong - a server may just be spinning up or down and fail during the handshake, and prevents retrying such downloads

  [Test plan]

  A test case has been added to the integration test suite that ensures
  handshake errors are retried upon configuration.

  [Where problems could occur]
  Transient errors do not cause an error exit from apt update, so scripts relying on errors from TLS handshakes in such situations will fail.
