Support aliases for `wp shell`

[schlessera]

It would be hugely useful to allow for the wp-cli.yml files to define "aliases" that work inside of the wp shell REPL.

These could be defined globally or per site, and would reduce the amount of typing necessary for heavy debugging/testing sessions. So, something like $obj = new \Vendor\Package\Module\AwesomeClass(); could be simplified by providing an alias like \Vendor\Package\Module\AwesomeClass => MyAwesomeClass, so that you can simply type: $obj = new MyAwesomeClass();.

The aliases could even support entire code snippets, for setup code you often need.

Can you share an example of how this might be formatted?

[schlessera]

It would probably look something like this:

shell:
    alias:
        - MyAwesomeClass: \Vendor\Package\Module\AwesomeClass

It should probably be smart enough to detect whether it is dealing with a class, a method/function or a variable, and produce the aliases accordingly.

It could throw warnings when aliases are ambiguous, like when it finds both a class as well as a variable that would match.
