Add option to exclude suspended domains/subdomains from tootctl domains crawl (#11454)
* Add "--exclude-suspended" to tootctl domains crawl This new option ignores any instances suspended server-wide as well as their associated subdomains. This queries all domain blocks up front, then runs a regexp on each domain. This improves performance over what may be the obvious implementation, which is to ask `DomainBlocks.blocked?(domain)` for each domain -- this hits the DB many times, slowing things down considerably. * cleaning up code style * Compiling regex * Removing ternary operatorrebase/4.0.0rc2

The --exclude-suspended (-x) option means that domains that are suspended
