Use Actions Permissions to clean up VBO operations

Currently, we display all VBO operations regardless of whether a user's permissions actually allow all of them. VBO ships with the Actions Permissions module to allow for more granular control of this.

I intend to enable this module and assign appropriate permissions to our roles.

These should be:

aegir administrator
execute Platform: Delete (hosting_platform_op_delete)
execute Platform: Lock (hosting_platform_op_lock)
execute Platform: Unlock (hosting_platform_op_unlock)
execute Platform: Verify (hosting_platform_op_verify)
execute Site: Backup (hosting_site_op_backup)
execute Site: Delete (hosting_site_op_delete)
execute Site: Disable (hosting_site_op_disable)
execute Site: Enable (hosting_site_op_enable)
execute Site: Reset password (hosting_site_op_login_reset)
execute Site: Verify (hosting_site_op_verify)

aegir client
execute Site: Backup (hosting_site_op_backup)
execute Site: Delete (hosting_site_op_delete)
execute Site: Disable (hosting_site_op_disable)
execute Site: Enable (hosting_site_op_enable)
execute Site: Reset password (hosting_site_op_login_reset)
execute Site: Verify (hosting_site_op_verify)

aegir platform manager
execute Platform: Delete (hosting_platform_op_delete)
execute Platform: Lock (hosting_platform_op_lock)
execute Platform: Unlock (hosting_platform_op_unlock)
execute Platform: Verify (hosting_platform_op_verify)
execute Site: Delete (hosting_site_op_delete)
execute Site: Disable (hosting_site_op_disable)
execute Site: Enable (hosting_site_op_enable)
execute Site: Verify (hosting_site_op_verify)
