Public packages are not displayed on `package definitions` tab for non-admin users with `manage_public_package` perms

[Kirill Zaitsev]

Steps for reproduce:
* Login to Horizon as an admin user
* Upload murano package
* Make the package public
* Create new non-admin user with permissions to edit public murano packages `manage_public_packages` (edit policy.json if necessary)
* Login to Horizon as new user
* Navigate to Murano -> Manage -> Package Definitions tab

Actual result:
User doesn't see public packages

Expected result:
User can see public packages

    Show 'Tenant name' column for non-admin users

    To identify own packages and foreign (public) packages,
    column with tenant teme is provided.
    It is shown for admin, and now enabled for non-admin.

    Since non-admin have no rights to identify tenant by id,
    'other' is used instead for non-user tenant.

    Show public packages for non-admin users

    But only if modification of public packages are allowed in policy file.
    Turn off managing public packagef for non-admin users by default.

    Currently non-admin users are able to see only their own packages
    despite of the policy setting.

    Corresponding tests were updated.
