MOBDOC-14 Add Antora structure to xamarin repo for docs

[pwright]

Motivation

Add antora structure to sdk for docs

JIRA: https://issues.jboss.org/browse/MOBDOC-14

[wei-lee]

The changes look fine. Any particular instructions on how to verify the changes?

[pwright]

@wei-lee I have some instructions at http://shiftgear.org/processes/latest/docs/antora.html
but dunno if that helps

[wei-lee]

I followed the instructions and looks like it is working. Although I noticed that this is creating a new docs dir, even though there is already a Documentations dir in the SDK already. Is that necessary?

[pwright]

@wei-lee could I suggest that we have a follow on task, to convert the existing doc from markdown to asciidoc and include it in the docs directory?

[pwright]

@wei-lee btw you could assign that follow on task to me ;) We could reuse documentation directory, but would make this repo different from all the others, that's what i'm trying to avoid

[wei-lee]

@finp we have a task this sprint to actually starting on writing the docs. I think we can progress the follow on task as part of that issue. Are you ok with that?

[pwright]

@wei-lee perfect

[wei-lee]

@finp I have updated the description of the JIRA issue to include the follow on tasks you have mentioned.

[wei-lee]

@StephenCoady I am ok to merge this if @finp is happy with it.
