Kayobe uses a number of virtual environments on the remote hosts for
python dependencies such as shade, python-openstackclient, docker, etc.
By default these are stored in /opt/kayobe/venvs/. Typically we do not
provide version restrictions when installing these packages, so over the
course of time they may become stale and incompatible.

This change installs the latest version of packages allowed by OpenStack
upper constraints.

It also adds a new variable, 'pip_upper_constraints_file', to set the
upper constraints file. The existing variable
'kolla_upper_constraints_file' now defaults to the value of
'pip_upper_constraints_file'.

Fixes an issue where the admin-openrc.sh and public-openrc.sh files
would not be generated when preparing a new control host environment for
an existing cloud. These files are now generated during 'kayobe control
host bootstrap' if the Kolla Ansible 'passwords.yml' file exists in the
Kayobe configuration.

Juniper physical network device configuration fails when running the
following command:

kayobe physical network configure --group switches

The error is as follows:

fatal: [switch]: FAILED! => {
        "msg": "Unknown host key [<key>] for [[<IP>]:830]"
}

This is due to a bug [1] in ncclient.

This patch avoids the issue by pinning ncclient to version 0.6.2 or
lower.

There is no need to connect controllers nodes to the storage management
network by default. It should only be used by storage nodes.

Kayobe is now a kolla deliverable [1], so should use the official
site for publishing release notes and docs.

Links will be updated once these have been published.
