Merge lp://staging/~sinzui/launchpad/person-owned-teams into lp://staging/launchpad

List teams a person owns.

Team owners are not necessarily team members. All code that lists teams
for people are based on membership. There is no way to discover which
teams a person owns. This is a problem for cases where a person leaves
an organisation -- the team owner does not show up when auditing,
and owners can add themselves back to the team to gain team privileges.

RULES

    Pre-implementation: no one
    * Add a method to IPerson to get the teams a person owns. The
      method must take a user argument to filter out private teams the
      observing user cannot see.
    * Add a related teams page to the related packages/projects group
      of pages. The page must batch the teams.

QA

    * Visit https://qastaging.launchpad.net/~
    * Verify there is a link to owned teams.
    * View the link's page.
    * Verify the page lists the teams.

    * Run this script:
    {{{
    from launchpadlib.launchpad import Launchpad
    lp = Launchpad.login_with(
        'testing', service_root='https://api.qastaging.launchpad.net',
        version='devel')
    person = lp.people['sinzui']
    teams = person.getOwnedTeams()
    for team in teams:
        print team.name

    lp = Launchpad.login_anonymously(
        'testing', service_root='https://api.qastaging.launchpad.net',
        version='devel')
    person = lp.people['sinzui']
    teams = person.getOwnedTeams()
    for team in teams:
        print team.name
    }}}

IMPLEMENTATION

I added getOwnedTeams to IPerson that return the teams for a Person that
a user is permitted to see. I exported it to use the requesting user as
the user passed to the method.
    lib/lp/registry/interfaces/person.py
    lib/lp/registry/model/person.py
    lib/lp/registry/tests/test_person.py

I added PersonOwnedTeamsView to the related-software group of pages. I
then added a link to the IPersonRelatedSoftwareMenu to complete the
integration.
