Bug description:
  [impact]

  upstream commit 7fdb237f5473cb8fc2129e57e8a0039526dcb4fd broke remote journal upload, because it added a check to verify the Content-Length header, but the upload may use Transfer-Encoding of 'chunked' which does
  not specify Content-Length.

  [test case]

  see comment 5

  [regression potential]

  this limits the Transfer-Encoding to only be either unspecified, or
  'chunked'.  Any other value will fail.  However, journal-upload.c does
  not ever use any other Transfer-Encoding than 'chunked', and this fix
  comes from upstream and has not changed since applied there.

  Any regression would likely result in the failure to upload a remote
  journal.

  [other info]

  the commit that caused this is not included in Bionic, and the commit
  to fix this is already in Eoan; this is needed only in Disco.

  I'm requesting that systemd 240 receive the fix in upstream PR 11953
  found here https://github.com/systemd/systemd/pull/11953

  This fixes remote journal shipping using systemd components. I believe
  only Disco (19.04) is impacted by this issue.
