Added new config:import:list and config:export:list commands. Fix no return on configImport method for config:import:single command

[bpresles]

Added 2 commands:

config:import:list

Takes a YAML file with list of config names to import. Allow to import restricted list of config names easily (rather than doing multiple config:import:single for each config name)

config:export:list

Takes a YAML file with list of config names to export. Allow to export restricted list of config names easily (rather than doing multiple config:export:single for each config name)

Also includes a fix in configImport method of config:import:single command that doesn't return boolean on success (making the success message not displayed).

@bpresles I like this idea but since we have config:import:single and config:export:single how about trying to merge functionality.

[bpresles]

@jmolivas
Yes why not. Would you prefer to merge this in existing config:import:single and config:export:single commands by adding for example a --list [configs list YAML file]?
Or create new commands name offering both functionality (in that case which names would you suggest?)?

Once you tell me you preference I'll work on it and create a new pull request (it will be cleaner).

[jmolivas]

@bpresles I think we can do something like this to merge with current config:import:single and config:export:single commands.

My first idea or recommended approach is to change ExportSingleCommand
https://github.com/hechoendrupal/DrupalConsole/blob/master/src/Command/Config/ExportSingleCommand.php#L62-L66

• Make config-name an option
• Make config-name an array InputOption::VALUE_IS_ARRAY
• Create an example YAML file to use it via a chain command
• Implement code similar to what you have on this PR to process multiple configurations.

commands:
  - command: 'config:export:single'
    options:
        config-name: 
          - core.extension
          - contact.settings

Add documentation how to use it:

drupal chain --file=path/to/multile-config.yml

NOTE: A chain command can read a YAML file and execute one or multiple commands previously defined on that YAML file.

Examples:

• https://github.com/hechoendrupal/drupal-console-core/blob/master/config/dist/chain/create-data.yml
• https://github.com/hechoendrupal/drupal-console-core/blob/master/config/dist/chain/site-update.yml

@bpresles still interested to make this happen?

[bpresles]

@jmolivas Yes sure. I didn't have much time these days to work on it. I'll look at it this week end.

[bpresles]

@jmolivas Just to keep you informed, I didn't have much time this week end finally. I hope to be able to work on it and finish it for the end of the week at most.

@jmolivas
I've done the merge. To avoid any compatibility issue with previous version, I've kept the original arguments (name and file for import:single, config-name for export:single) adding a new "config-names" option that allows the use of these commands with chain command and a list of config names.

[jmolivas]

@bpresles Thanks for refactoring I have some comments:

• Lets use only one argument make config-name have the functionality of config-names and remove config-names.

• Remove the files export-config-list-sample.yml and import-config-list-sample.yml
  We can add those as examples to the docs instead.

[jmolivas]

I saw some other old issues to fix like, argument names ons is called config-name the other only name

[jmolivas]

I will go ahead and have this merged and I will send a PR with mentioned fixes.
