Flags With Multiple Values Are Not Correctly Handled (e.g., mtaDeployParameters of cloudFoundryDeploy)

The following code seems not to do anything as the return value is the same for matches within " and without.

project-piper-action/src/utils.ts

Line 15 in ca48370

// Preserve the double quotes around arguments

Furthermore this code doesn't support flags which have more than one value (e.g., --mtaDeployParameters of step cloudFoundryDeploy).

I tried to specify the --mtaDeployParameters but the arguments are not correctly propagated to the piper binary call.
I either got a list of invalid flags for the piper binary like -f, --version-rule, 'ALL' or their are wrapped inside " like "-f --version-rule ALL --skip-testing-phase --delete-services" which cannot be handled by the cf deploy command executed by piper cloudFoundryDeploy.

I am not sure why it is important to preserve the " in the argument value.
Maybe it makes sense to use a library like minimist for proper command line option parsing.

Our workaround for now is to define another job so that we can define the values in the .pipeline/config.yml file via the stage overwrites:

stages:
  '<Job Id>':
    org: '<some other value than in the step configuration>'
    space: '<some other value than in the step configuration>'
    mtaExtensionDescriptor: '<some other value than in the step configuration>'
    mtaDeployParameters: '-f --version-rule ALL --skip-testing-phase --delete-services'
    mtaPath: '<some other value than in the step configuration>'
