wait: add --ignore option

Browse Source 
In the recent past, I met the frequent need to wait for a container to
exist that, at the same time, may get removed (e.g., system tests in [1]).

Add an `--ignore` option to podman-wait which will ignore errors when a
specified container is missing and mark its exit code as -1.  Also
remove ID fields from the WaitReport.  It is actually not used by
callers and removing it makes the code simpler and faster.

Once merged, we can go over the tests and simplify them.
