Nova CLI help should only use one of "instance"/"server"

[Jakub Ružička]

Terms "instance" and "server" are used interchangeably in `nova` help.

Only one term should be used to avoid confusion.

I propose going with "instance", but that would require renaming/deprecating/aliasing "hypervisor-servers" command, which is only nova command with "server" in it.

$ nova | grep "instance\|server"

[Andrew Laski (alaski)]

We should go with server over instance. Instance is an internal concept to Nova while server is the consumer understanding of things. Also:

$ nova help | grep "instance" | wc -l
8
$ nova help | grep "server" | wc -l
47

    Make nova CLI use term "server" where possible

    nova client was using terms "server" and "instance" interchangeably
    which was very confusing.

    This patch uses "server" where possible without touching the API.

    Note that there are actions (instance-action, instance-action-list) and
    arguments (--instance-name, --num-instances, ...) with "instance" in their
    name which can't be changed easily.

    Closes bug 1156648
