Add --limit option to docker search

Browse Source 
This fix tries to address the issue raised in #23055.
Currently `docker search` result caps at 25 and there is
no way to allow getting more results (if exist).

This fix adds the flag `--limit` so that it is possible
to return more results from the `docker search`.

Related documentation has been updated.

Additional tests have been added to cover the changes.

This fix fixes #23055.
