Update the docs to make it clear that .socket will be slow to respond to
the first request, and to use .service to speed it up.
(cherry picked from commit 83e5f3f885)
(cherry picked from commit c2f96b3d3b)
This updates the documentation to include composer-cli instead of curl,
warnings about SELinux and needing the RHEL 7 Optional package repo, as
well as other documentation improvements from the master branch.
This drops support for the TCP port and switches to using a socket at
/var/run/weldr/api.socket
Also add the start of some docs for lorax-composer.
--host and --port argument have been removed.
--group sets the group name to use for access to the socket and its
parent directory. Defaults to 'weldr'
--socket sets the full path to the socket to create. Defaults to
'/var/run/weldr/api.socket'
