FoD: remove all positional parameters and replace with options

[kadraman]

Given fcli <module> <entity> <action> <param>, does <param> represent <entity>? (i.e., in fcli ssc artifact download <id>, <id> refers to the artifact entity?

Should we maybe get rid of positional parameters altogether, or use them only in very specific cases like ‘get’ commands? Users now need to understand whether to use --appversion <appversion> or just <appversion>; might be easier to just always have --appversion …

It’s not clear what FCLIDEFAULT* environment variable name to use for specifying a default value for positional parameters

We could potentially have exclusive --app <name or id>, --app-id <id> and --app-name <name> options to allow for numeric app names; this is more difficult/impossible with positional parameters

[kadraman]

Proposal is to remove positional parameters where they are confusing. This is likely in the following areas:

• ~on entity creation - it is not clear where/what the positional parameter is and there are many parameters~
• on scan import - there are a number of xxx-scan import commands where fileName is the positional parameter, this is confusing as its the scan entity.
