• Add a new aliases configuration entry in the wp-cli.yml file
• Allow to use --alias=foo instead of @foo to use an alias
• Keep the classic arg notation working
• Works properly with the local and global configs merged together even if both styles are used

New wp-cli.yml config entry aliases

Example of a working configuration.

Global config file

@test-1:
  ssh: user@domain-test.com:~/web

Local config file

@test-2:
  ssh: user@domain-test-2.com
  path: ~/web

aliases:
  test-3:
    ssh: user@domain-test-3.com
  @test-4:
    ssh: user@domain-test-4.com

When using the aliases config entry, there is no need to prefix the alias name with @. Every key in this hash is recognized as a valid alias name.

@all and other group features seem to be working properly (though I never had them working on Windows due sur sub-PHP process command not knowing where to find the ssh command).

New CLI parameter --alias

Instead of using the @alias positional parameter, you can now use the --alias=foo param.
This improves the Windows CLI compatibility as @ is a reserved char (like $ or `) and need to be quoted to work properly.

--alias= param works well with both classic alias definition and the new. And it works exactly the same for groups.
