c399447b81 Fix a problem with using a mirror as the primary url
Because of how Anaconda is run it needs to be passed a baseurl (using
--repo on the anaconda cmdline), not a mirrorlist url. This fixes it so
that the first mirror is used if the main repository is using a
mirrorlist.

a1427b1a31 Set the HOME variable to a directory the uid can access
libgit2 will look for $HOME/.gitconfig after dropping root privileges so
this needs to be accessible to the user.

4ae2e1450d Exit on uid/gid errors before checking directory permissions
If the uid/gid check fails there is no sense in trying to examine the
ownership or permissions.

8da6214e10 Add a test mode to /compose
This will allow testing without having a full system setup with
anaconda, if ?test=1 is passed to the POST /compose command it will wait
10 seconds instead of running Anaconda, and then raise an error to
generate a failed build.

Passing ?test=2 will also wait 10 seconds instead of running Anaconda,
but will finish successfully.

ff7d36bcbc Add /compose/log/ API to retrieve the end of the build log
This allows the client to request the end of the anaconda.log during and
after a build. The amount of data returned can be set by adding
?size=<kbytes>

Output is raw bytes, starting on the next available line boundry.

072aa720ff Add /compose/cancel API to cancel a running build
If the build hasn't started yet (state is WAITING) try removing the
symlink to it. If this succeeds, delete the partial results directory.

If the build makes it to RUNNING then it writes a CANCEL file in the
results directory. The callback that is passed to execWithRedirect
catches this, causing a SIGTERM to be sent to anaconda. It then exits
and cleanup happens normally. The partial results directory is then
removed.

32db249538 Add tests for yumbase and update how we inspect boolean options
.get_default() returns string so make sure we're actually parsing
the value as boolean and not evaluating a non-empty string in a
boolean context (which will always return True)

6a95a314e9 Add API routes for downloading build results
Also fix a bug with the name of the queue status in the status results
(it is now 'queue_status' not 'status' which is used for error
responses).

This adds the following routes:
 - /compose/metadata/<uuid> to retrieve a .tar of the build metadata
 - /compose/results/<uuid> to retrieve .tar of all of the build results
 - /compose/logs/<uuid> to retrieve a .tar of just the logs from the build
 - /compose/image/<uuid> to retrieve the output image from the build

ed03ac7524 Add /compose/info route to retrieve details about a compose
The results is a JSON string with the following information:

* id - The uuid of the comoposition
* config - containing the configuration settings used to run Anaconda
* recipe - The depsolved recipe used to generate the kickstart
* commit - The (local) git commit hash for the recipe used
* deps - The NEVRA of all of the dependencies used in the composition
* compose_type - The type of output generated (tar, iso, etc.)
* queue_status - The final status of the composition (FINISHED or FAILED)

d3a9ec3002 Return the commit id for the recipe being read
This adds returning the commit id from read_commit, and a new function
read_recipe_and_id() that returns the commit id and the recipe in a
tuple.

If the commit is passed in, it is used as is. If no commit is passed in
it finds the most recent commit for the file on the selected branch and
returns that.

Missing recipes now raise a RecipeError with an informative message.
eg. "No commits for missing-recipe.toml on the master branch."

version.

67da4d6971 Add building an image, and the /compose route to start it
This adds the ability to build a tar output image. The /compose and
/compose/types API routes are now available.

To start a build POST a JSON body to /compose, like this:

{"recipe_name":"glusterfs", "compose_type":"tar", "branch":"master"}

This will return a unique build id:

{
  "build_id": "4d13abb6-aa4e-4c80-a671-0b867e6e77f6",
  "status": true
}

which will be used to keep track of the build status (routes for this
do not exist yet).

e2f4674fb3 Add basic composer queue handling
The queue is in /var/lib/weldr/queue/new by default. It watches the
directory for new symlinks (to /var/lib/weldr/results/<dirname>) and
handles running anaconda on the kickstart found in final-kickstart.ks
inside the symlinked directory.

0ce4197a1e Change compress to use communicate instead of wait
Also move default_image_name into imgutils so it can be used in other
places.

When running from lorax-composer the wait() call wasn't waiting until
the tar was finished. I think this is due to gevent monkey-patching
something. Using communicate() solves this problem.

377f5e4124 Switch the API to use a Unix Domain Socket
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'

916a001d73 Add support for other branches to the routes
Passing ?branch=<branch-name> will use the specified branch instead of
master.

The new branch will not exist until a /recipes/new?branch=new-branch
POST is made. At that time the branch will be created based on the
current master branch and the new commit will be added to it.

176b12dd8c Fix depsolving empty recipes
- Fix `projects_depsolve()` to not consider a successful empty response
   (rc == 0) as an error.
 - Fix recipe_from_dict() to default modules and packages to empty lists
   instead of `None`, to avoid a Python-ism in the API for consumers and
   stay compatible to the bdcs API.

Fixes #290
