When generating CIB syntax, elide initial in some cases

[krig]

This is something I worked on this weekend, but now that I have it working, I don't know if I really think it is a good idea. This would make eliding the "params" or "attributes" the default even when displaying the configuration, except when there are multiple params or attributes tags.

Dejan, how do you feel about this? I'm apprehensive, because although I think it improves the readability of examples like

primitive vip IPaddr2 ip=192.168.0.200

...there are other cases that aren't as clear cut, and it makes the generated syntax context-sensitive, not just the accepted input (where I don't think there are any downsides to allowing it).

So right now I am inclined to throw this away :P

I'm always for being more concise. Now, keywords such as "params" or "meta" served to signal what follows. BTW, meta attributes can be listed _before_ params in an element and crmsh should also preserve that order. Otherwise, let me think about it some more. P.S. I've always hated the "params" keyword :->

In the case of meta attributes listed before params, it will generate the old/current style output. So that case should work fine. It is only if the first element is a params list, AND if there is only one params list, that it skips the params keyword.

BTW, I have also been thinking about handling the "meta target-role=started|stopped" case in a special way, and replace it with for example the special keywords "::start" | "::stop". Not sure about this either :) (the :: is one suggestion, other suggestions are =>start, =>stop

So

primitive p0 Dummy state=1 =>start

instead of

primitive p0 Dummy params state=1 meta target-role=Started

Another idea I have is to rename "primitive" to "resource". primitive seems like a terrible XML-ism that has crept into the CIB syntax ;) But I don't know if this is something worth changing. The resource concept also includes groups and clones, but I think calling primitives resources makes sense.
