[wildfly-dev] syntax enhancement for cli boolean operation parameters

[Alexey Loubyansky]

Just a brief announcement of a syntax enhancement in the CLI for boolean 
parameters in operation requests. Just to advertise it and avoid 
confusion with the changes in the tab-completion.

It's been quite some time ago since somebody (probably Kabir) gave me an 
idea of how we could enhance the syntax for boolean parameters set to true.
I.e. instead of typing :read-resource(recursive=true) all the time 
:read-resource(recursive) should be enough.

So, the presence of a boolean parameter name w/o a value would mean the 
parameter is implicitly set by the user to true.

While I liked the idea, I never actually implemented it. So I mentioned 
it to Jeff (jfdenise) who is getting his hands on the CLI now and he 
went ahead and did it.

So now

:read-resource(recursive) is equivalent to :read-resource(recursive=true)

Both syntaxes are allowed.

False is still set explicitly, i.g. :read-resource(recursive=false)

The absence of the parameter still means the parameter was not provided 
by the user.

Tab-completion has also been enhanced to suggest the shorter form for 
true and still suggests the explicit form for false.

We hope you'll like it. Thanks Jeff for actually implementing it!
