When we use "--property" parameter, client get lists these the
value is string type, but the type of the value 'is_domain'
should be boolean, so we should judge it and parse it.
The patch parse string to boolean for value 'is_domain'.

Conflict:
  Direct backports of this patch fail because the original tests
  proposed to the Victoria (master) branch included keystone
  ``options``. Support for ``options`` was added in:

    I9c3bdd741f28bf558267fb217818d947597ce13e

  This backport removes the ``options`` key from the expected values in
  the tests since feature support for ``options`` isn't going to be
  backported. Otherwise, the functionality of this change is fully
  tested like it is on later releases.

This change adds tags functionality for projects in keystone. A user
can add a single tag with "--tag", chain "--tag" to add multiple
tags, or clear tags with "--no-tag".

Due to a default Keystone policy until Newtown,
and the use of resource_find, non-admins are unable
to list their own projects.

This patch bypasses this problem while also introducing better
UX for non-admins wishing to get their project list.

'openstack project list' retains the default of 'list all projects'
but on a forbidden error will default instead to 'list my projects'.
This way for non-admins 'list my projects' feels like the default
without breaking the expected admin default.

Adding the '--my-projects' option allows admins to easily list their
own projects or allows non-admins to be explicit and bypass the
forbidden error fallback.

The parents_as_list and subtree_as_list query parameters limit the
result to only parents and subtree where the user making the call has
role assignments in. Since OSC only displays the IDs, the call would be
the same as the similar *_as_ids queries, the difference is that the
later doesn't enforce the role assignments (making it more useful).

Output example by using this patch:

$ openstack project show --children root
