List image API fail with direct name query if name includes ":" colon

[Masahito Muroi]

If image name includes ":" (colon) in its image name, ?name=<image name> query filter doesn't work. The split_filter_op[1] always treats ":" character as a separator, so the ":" in the name is wrongly handled.

How to Reproduce
1. Create an image which name includes ":"
2. Make an API request to List Image API using ?name=<image name> query

$ openstack image list --name "Rocky Linux 9.3:20240315"
BadRequestException: 400: Client Error for url: https://glance.endpoint.com/v2/images?name=Rocky+Linux+9.3%3A20240315, Unable to filter by unknownoperator 'Rocky Linux 9.3'.<br /> <br />
