Title:
  revert tls security level back to 1

Status in openssl package in Ubuntu:
  Fix Released
Status in openssl source package in Cosmic:
  Fix Released
Status in openssl source package in Disco:
  Fix Released

Bug description:
  [Impact]
  * increase minimum default tls security level from 0 to 1, as is the default upstream

  [Test Case]

  * generate 80bits TLS certificate and attempt to use it

  * with prior openssl it should work, but with this update it should
  fail

  [Regression Potential]

  * This increases the minimum required certificate/keys sizes and
  algorithms, back to what Bionic GA openssl 1.1.0 shipped as. It also
  now will match upstream default. It is still lower than Debian's
  default that raises it to 2 by default.

  * Cosmic GA shipped with TLS_SECURITY_LEVEL 0, meaning pretty much any
  weak keys were accepted. With this change keys lower than 112 will be
  rejected, which are considered to be too weak to be useful by most CAs
  out there.
