Rename `--to-static` to `--static`, issue warnings for duplicate IPs.
Rename `--to-static` to `--static`, issue warnings for duplicate IPs.

Warnings about duplicate IPs are only printed when static output
is being generated and are written to stderr.  For `--list` and
`--host` warnings are suppressed since Ansible will discard output
on stderr from an inventory script, anyway.  It would not mess things
up but it won't be visible either.
