Title:
  Add TLS support

Status in busybox package in Ubuntu:
  Fix Released
Status in busybox source package in Focal:
  Fix Released

Bug description:
  [Impact]

   * busybox in the initramfs provides wget applet that is used by casper for netboot support
   * It does not support https at the moment, but it is desirable that it does
   * There is built-in TLS code, or "fork & execute openssl"
   * Enable the later one, and optionally include /usr/bin/openssl & certs, when building casper-like initrds which should support netboot.

  [Test Case]

   * Boot casper created initrd, with break=bottom
   * Configure dhcp based networking
   * Attempt to wget https://start.ubuntu.com/connectivity-check
   * It should succeed

  [Regression Potential]

   * The openssl codepath is optional in busybox wget, and we only include openssl & certs for casper.
   * The casper based initrd will grow in size, due to inclusion of openssl & certs

  [Other Info]
   
   * Parity with d-i, which includes https support already
