Add packageId to force:package:version:report response

[fischerp]

Is your feature request related to a problem? Please describe.
I need to get the packageId when executing the following command.
sfdx force:package:version:report -p "myPackage" --json
or
sfdx force:package:version:report -p "04t50000000AbcD" --json

What are you trying to do
I want to get the package id from a specific attribute called packageId. Currently the Id is available on the message, but there is no easy way to extract it.

Describe the solution you'd like
I want to execute sfdx force:package:version:report -p "myPackage" --json or sfdx force:package:version:report -p "04t50000000AbcD" --json and I want to have an easy way to get the ID from the response.

Current return:
{"message":"The Subscriber Package Version Id 04t50000000AbcD is invalid, ...

Expected result:
{"packageId":"04t50000000AbcD","message":"The Subscriber Package Version Id 04t50000000AbcD is invalid, ...

Describe alternatives you've considered
A poor alternative would be extract it from specific parts to the current response or by reading the sfdx-project.json file to get the ID.

@sfdx-db-gmail, Please take a look at this feature request for Packaging

@fischerp - can't you parse force:package:version:list and get the 04t from there? Cc @clairebianchi

Thanks @sfdc-db-gmail and @clairebianchi, I'm parsing the response and extracting the ID, but I don't think it's a good solution because I would be relying on a message.
The real problem is that I didn't find any native way to list packages and aliases from local "sfdx-project.json", for sure there is work around to get the Alias and Id.
The feature proposed by @jefersonchaves (#12) would do the trick, but that one is a new implementation, while this one requires the exposure of an extra variable.

If you're trying to get information out of a command, instead of parsing the message, use --json for a structured result (and one that should should be stable where we can't remove properties)

That should be easily parseable with something jq https://jqlang.github.io/jq/
