OVSDB transaction timeout parameter needs to be configurable

[Gal Sagie]

Currently the transaction timeout is taken from a context object that has a vsctl_timeout attribute
this method is confusing for other users of this class (like OVN) and should be configurable in a different way

    Enhance OVSDB Transaction timeout configuration

    OVSDB Transaction currently takes the timeout parameter
    from a context object that assume to have a vsctl_timeout attribute
    This doesnt fit well for other users of this class (like OVN)

    This fix configure the transaction timeout in a more common way
