Exporter: Add support for special selectors in -listing and -services.

[alexott]

As we get more services added to the exporter, it's becoming tedious to enumerate all necessary services to list and to export when you need a granular selection - for example, I want to list everything except Unity Catalog objects and export all dependencies except users and groups.

Proposal:

1. Add support for negate operator when specifying services, like: -uc-volumes, -users,-groups, etc. (all selector will be implied here)
2. (optionally) Add support for all selector to specify all services, so we can say -listing all,-uc-catalogs,-uc-shares... It could be implicit when we use the first option, but it may improve the readability of command-line arguments
3. Add support for services classes, like, uc, sql, etc. so we can enable or disable multiple services at once.
