Gerrit appears to have had some visual updates since the screenshots
in the quick-start guide were taken. This is just an updated
screenshot which shows what gerrit currently looks like

With the old code using humaized time it appears to always round down.
This means a job that will run for an hour and 45 minutes is estimated
to complete in an hour. With these sorts of estimates it is my
experience that it is better to over rather than under estimate as
people will get frustrated if it takes twice as long to get their
results as is stated.

To address this we can provide a more specific estimate. We can say "One
hour 45 minutes" instead of "an hour". This gives users a much better
indication of when they can expect results.

The quick-start guide uses yum instead of dnf for installing
packages in Fedora to prepare for running Zuul. Also, git-review
is now packaged in Fedora and doesn't need to be installed via pip
anymore.

Instead of preventing newer version which would create conflicts, we
just avoid the known broken versions.

Avoid often timeouts which slowed merging other patches.

This should buy us enough time to also optimize the tests and reduce
their duration.

With help from TristanC, this should create a tooltip when users hover
over the status bar of a running job, that displays the estimated time
left.

For GitHub events, zuul-web also needs a connection to GitHub.

Profiling shows git operations take significant time. They are done in
sub directories of a temporary directory optionally set via environment
variable ZUUL_TEST_ROOT.

Set ZUUL_TEST_ROOT at the jobs level.
When set, have test-setup to create a tmpfs.

Config files are written using file handles which are never closed.
Under python 3.4 or later, that causes ResourceWarning warnings to be
emitted.

test_bubblewrap open files under /proc but never closes them. Under
python3.4 or later, that causes a ResourceWarning to be emitted:

ResourceWarning: Enable tracemalloc to get the object allocation traceback

A jitter value for the periodic pipeline in
`test_timer_with_jitter` renders this test
flaky, since we can not know when exactly the
pipeline gets triggered.
This change makes the test case deterministic
by replacing sleeps with `iterate_timeout`.

TestMergerRepo.test_repo_repr attempts to clone from a remote named
"remote". Since that is most probably is never reacheable, it would
times out after 60 seconds, only to then assert against the object
representation.

The test has little value by itself, the Repo.__repr__ method is
explicit. In the future, git blame can be used to identify why
local_path is added to the repr (id is not enough to disambiguate).

Previously these tests ran a number of jobs serially checking them each
in turn. Speed this up by starting all of the jobs in parallel then
collecting the results. On my local 2 cpu machine running a single test
with this change has that test running in about 60% of the time compared
to the preexisting code.

This reverts commit 10190257f1.

This appears to be related to a memory leak seen in production on
OpenDev.  We don't have any data, other than reverting this commit
restored memory performance to normal.

Linters are only used by the 'pep8' virtual environment, we do not need
them in other test environment.  Also 'pep8' only requires the three
linters it used and the other modules are not needed.

Move the pep8 dependencies to the pep8 testenv.

Since version 2.0.0, `stestr run` supports passing `--slowest` to show
the slowest tests.

Change-Id: I015781402962e5518f650057f32ba8c7f168aea9

In TESTING.rst, the `stestr run` incorrectly used `-t` to pass a test
filter. The option is common to `stestr` and is used to specify the test
path used for unittest discovery. It is already configured in
`.stestr.conf`:

  [DEFAULT]
  test_path=tests/unit

One just has to pass the fully qualified test name as an argument.

- Adds usage example for using role inside jobs before the long detailed
  explanation in order to avoid need to scroll to see it. Also very
  useful if someone shares a link to that section
- Transforms the not implemented galaxy notice into a warning and moves
  it inside the galaxy section in order to avoid confusions. The
  previous layout confused at least two people reading the roles section.
