Cleanup help strings and docs for clarity and to keep things consistent:
* --limit metavar should be <num-resource> to indicate what is being counted
* --marker metavar should be <resource> or <resource-id> to indicate the
type of value being specified
* <*-ip-address> metavars should be just <ip-address> as there is no difference
in format between fixed and floating IPs
* Move all occurances of '(name or ID)' to end of help text

In the current doc, the command examples are like
"os server create" but the acutal command should
be started with "openstack" instead of "os", it
is misleading to first time users.

try and add some consistency with the show and delete commands.
replace 'show x' with 'display x'
change 'delete a y' with just 'delete y'
