Subject: Use lighttpd for the trove http services.

- Add a configuration file to lighttpd. The max-procs for the
  read-only cache server is bigger than the writable cache server,
  as is expected to have a bigger load. Although the max-procs set
  is low, each fastcgi process supports multiple connections, that
  accordingly flup source code is equal to the maximum number of
  open file descriptors that a process can have.

- Remove morph-cache-server systemd units. The servers will be
  spawned by lighttpd as fcgi processes.

- Make cgit to be served by lighttpd instead of busybox httpd.
