    Be clear about hypevisors.search used in a few CLIs

    The following CLIs are doing a pattern match on the hypervisor
    hostname when getting servers:

    1. nova host-evacuate
    2. nova host-evacuate-live (terrible name)
    3. nova host-servers-migrate
    4. nova host-meta (terrible name)

    The fact that the hypervisor host(s) are looked up using
    a pattern match is not clear in the help string for the host
    argument.

    This makes the help more clear and adds a warning about being
    specific if you only want to target a specific host for these
    operations.

    In a later change we may modify the behavior in these CLIs which
    allow you to find hypervisors via pattern matching, but for now
    we should at least update the help text so we can backport it.
