Replace openstack.org git:// URLs with https://

This is a mechanically generated change to replace openstack.org
git:// URLs with https:// equivalents.

This is in aid of a planned future move of the git hosting
infrastructure to a self-hosted instance of gitea (https://gitea.io),
which does not support the git wire protocol at this stage.

This update should result in no functional change.

For more information see the thread at

 http://lists.openstack.org/pipermail/openstack-discuss/2019-March/003825.html

+Before you install and configure the Infrastructure Optimization service,
+you must create a database, service credentials, and API endpoints.
+
+1. Create the database, complete these steps:
+
+   * Use the database access client to connect to the database
+     server as the ``root`` user:
+
+     .. code-block:: console
+
+        $ mysql -u root -p
+
+   * Create the ``watcher`` database:
+
+     .. code-block:: console
+
+        CREATE DATABASE watcher CHARACTER SET utf8;
+
+   * Grant proper access to the ``watcher`` database:
+
+     .. code-block:: console
+
+        GRANT ALL PRIVILEGES ON watcher.* TO 'watcher'@'localhost' \
+          IDENTIFIED BY 'WATCHER_DBPASS';
+        GRANT ALL PRIVILEGES ON watcher.* TO 'watcher'@'%' \
+          IDENTIFIED BY 'WATCHER_DBPASS';
+
+     Replace ``WATCHER_DBPASS`` with a suitable password.
+
+   * Exit the database access client.
+
+     .. code-block:: console
+
+        exit;
+
+2. Source the ``admin`` credentials to gain access to
+   admin-only CLI commands:
+
+   .. code-block:: console
+
+      $ . admin-openrc
+
+3. To create the service credentials, complete these steps:

+   * Create the ``watcher`` user:
+
+     .. code-block:: console
+
+        $ openstack user create --domain default --password-prompt watcher
+          User Password:
+          Repeat User Password:

+          | Field               | Value                            |
+          +---------------------+----------------------------------+
+          | domain_id           | default                          |
+          | enabled             | True                             |
+          | id                  | b18ee38e06034b748141beda8fc8bfad |

+          +---------------------+----------------------------------+
+
+
+   * Add the ``admin`` role to the ``watcher`` user:
+
+     .. code-block:: console
+
+        $ openstack role add --project service --user watcher admin
+
+     .. note::
+
+        This command produces no output.
+
+   * Create the watcher service entities:
+

+          +-------------+----------------------------------+
+
+
+4. Create the Infrastructure Optimization service API endpoints:
+
+   .. code-block:: console
+
+      $ openstack endpoint create --region RegionOne \
+        infra-optim public http://controller:9322

+Infrastructure Optimization service overview
+============================================
+The Infrastructure Optimization service provides flexible and scalable
+optimization service for multi-tenant OpenStack based clouds.
+
+The Infrastructure Optimization service consists of the following components:
+
+``watcher`` command-line client
+  A CLI to communicate with ``watcher-api`` to optimize the cloud.
+
+``watcher-api`` service
+  An OpenStack-native REST API that accepts and responds to end-user calls
+  by processing them and forwarding to appropriate underlying watcher
+  services via AMQP.
+
+``watcher-decision-engine`` service
+  It runs audit and return an action plan to achieve optimization goal
+  specified by the end-user in audit.
+
+``watcher-applier`` service
+  It executes action plan built by watcher-decision-engine. It interacts with
+  other OpenStack components like nova to execute the given action
+  plan.
+
+``watcher-dashboard``
+  Watcher UI implemented as a plugin for the OpenStack Dashboard.

+The Infrastructure Optimization service (watcher) provides
+flexible and scalable resource optimization service for
+multi-tenant OpenStack-based clouds.
+
+Watcher provides a complete optimization loop including
+everything from a metrics receiver, complex event processor
+and profiler, optimization processor and an action plan
+applier. This provides a robust framework to realize a wide
+range of cloud optimization goals, including the reduction
+of data center operating costs, increased system performance
+via intelligent virtual machine migration, increased energy
+efficiency—and more!
+
+Watcher also supports a pluggable architecture by which custom
+optimization algorithms, data metrics and data profilers can be
+developed and inserted into the Watcher framework.
+
+Check the documentation for watcher optimization strategies at
+https://docs.openstack.org/watcher/latest/strategies/index.html
+
+Check watcher glossary at
+https://docs.openstack.org/watcher/latest/glossary.html
+
+
+This chapter assumes a working setup of OpenStack following the
+`OpenStack Installation Tutorial
