neutronclient icehouse gate failed with AlreadyAttachedClient not found in Horizon

[Akihiro Motoki]

gate-tempest-dsvm-neutron-src-python-neutronclient-icehouse for neutornclient fails in Horizon test [0].
Removal of AlreadyAttachedClient [1] causes the failure.

The current devstack tries to install python-neutronclient from git even if the version requirement is not satisfied.
We need to revert the above commit and it is better to wait for Icehouse EOL.

    Revert "Remove unused AlreadyAttachedClient"

    The removal of AlreadyAtatchedClient exception from neutronclient
    suddenly causes the failure of neutronclient icehouse job.
    It is better to wait the removal of the exception until Icehouse EOL
    (which will come soon).

    This reverts commit 30b198edec988d7c969c1edd4a2754bd9c9c79f4.

    Remove unused AlreadyAttachedClient

    This is a revert of revert of the original "Remove unused
    AlreadyAttachedClient" (30b198edec988d7c969c1edd4a2754bd9c9c79f4).

    The removed exception was referenced in Horizon Icehouse code
    and Icehouse is now EOL, so we can remove it safely now.

    This reverts commit d6cfd34e13426b88b40cb6ef7fdcd60d9b7dcb6b.
