Add `--exact-match` option for listing data sets

[t1m0thyj]

Is your feature or enhancement request related to a problem or limitation? Please describe

As a user who wants to list data sets, sometimes I want an exact match that doesn't include additional ds qualifiers.

Describe your enhancement idea

Received the following user request:

Sometimes we do have backups such as .RULES.BKP, but wouldnt want to grab those as they’re not live OPS/MVS rulesets

In some cases, matching only hlq.*.rules without returning hlq.*.rules.xyz would be preferred.

Describe alternatives you've considered

File an RFE with z/OSMF to add an exact match option that would prevent append .** to the ds pattern on the server side.

Provide any additional context
