This enables gnocchi-amqp daemon.

Which listens to metrics from collectd amqp1 write plugin.

remove workaround... or we can hit revert on original

requests 2.18.4 has requirement urllib3<1.23,>=1.21.1, but you'll have
urllib3 1.23 which is incompatible.

This explicits set the urllib3 version until requests release a fixed
library

Gnocchi requires 2.0.0 and not 1.2.0 since a while now.

This is done even we will drop it soon for helping packager.

redis-py has a python and c parser[1]. install the c parser. it offers
~10%-90% performance improvement depending on task using benchmark from
redis-py[2].

This allows to inject measures and maybe process them in a single tool. This is
useful to generate load to test metricd and also profile the processing code.

Closes: #852

All pbr interesting features (the seutp.cfg) have been implemented in
setuptools since version 30.3.0 (8 Dec 2016).
Also pbr will break us soon and force us to found a new solution
to generate things during setup.py steps.
https://github.com/gnocchixyz/gnocchi/issues/755

When you use pbr you cannot override most of the cmdclass. So we cannot
make our hooks working anymore.

Generation of ChangeLog and AUTHORS are done during egg_info.
gnocchi-api script is created on the fly with the right python header

Package file listing and package version is done by the pypa maintained
setuptools_scm.

This may impact downstream packaging as setuptools versions are a bit
old:
* xenial: 20.7
* zesty: 33.1.1
* centos7/rhel7: 0.9.8 ... really ?
* rdo queen: 22.0
* rdo rocky plan to 38.6

Closes-bug: #755

The docs target is run in Travis so we should be good. No need to run it here.

* https://review.openstack.org/532773 merged the gnocchi tempest
  plugin into telemetry tempest plugin. Let's remove it in the
  favor of same.
* https://review.rdoproject.org/r/11161 packages the telemetry
  tempest plugin.
* Keeping /gnocchi/tests/functional_live/gabbits{live.yaml,
  search-resource.yaml} as they are shared with tempest as
  well as for ensuring gnocchi-api/metricd.

This change adds a new type of attribute for resource: datetime.

Last keystonemiddleware have some missing dependencies.

Ban this version for now

Now that the `ceph` flavor is gone, let's use `ceph` for the recommended
approach and `ceph_alternative` for the other one.

gabbi allows to write custom value checker since 1.37.0.

This change uses that to check that .NAN is NAN.

This change reorganizes aggregates code.

* gnocchi.aggregates becomes gnocchi.deprecated_aggregates
* gnocchi.rest.cross_metric becomes gnocchi.rest.aggregates.processor

operate_aio_write_op have been added on Ceph 12.2

Closes #412

we don't necessarily need to load the same stuff for each service.
this way we can customise how we prepare each service and what libs
they need.

Since all drivers are based on Carbonara and there's no (more) plan to not do
that, this patch simplifies dependency by requiring tooz and lz4 as base
requirements.

As the wise Mehdi once said: "nobody reads documentation".
Everybody wants to run a daemon for the API server and everybody wants to run
`gnocchi-api'. Then let's provide it as a wrapper around uwsgi, so it's a fast
and performant HTTP by default.

Sem-Ver: api-break

So we have uwsgi pulled.

Oslotest is OpenStack specific and we actually don't use any of its feature
except stdout redirection and log silencing, which is really provided by
`fixtures' and `daiquiri'.
Remove it and use testtools directly. This avoids having OS_* variables used
everywhere and makes sure we don't pull dependencies we don't need (mox3,
os-client-config, etc).

Some extra dependency in pifpaf are now set as flavors, such as ceph.

Authentication can be delegated to a frontend webserver/middleware, that
will ensure that REMOTE_USER env is set.

SQLAlchemy now logs a warning if the driver is not correctly set in the URL.

Fixes #56

The `operate_aio_write_op` method is unavailable before that version.

A couple of fix for the docker image used by travis:

* locale package is no more installed by default
* liberasurecode-dev is required, now
* sphinx >= 1.6.0 have broken sphinx-versioning
* Don't use sphinx math module

support ability to change sacks via command line. will set new
sack value and clear any old sacks (if applicable). backlog must
be empty to change value.

Change-Id: Icf74b081e4cfaaaa607a5b9c684cbad4b8ecc006

by default we use sql as coordinator but gnocchi has high locking
requirements becuase of number of sacks which far exceeds default
100 connection limit of sql. switch to use redis as lock manager
instead.

as we move to multiple buckets, we will let each worker figure out
it's whether a bucket needs to be processed and thus we don't need a
central scheduler to distribute work around. for now, all workers
will go ham and work on same bucket.
