docs: aoe: convert docs to ReST and rename to *.rst
There are only two files within Documentation/aoe dir that are documentation. The remaining ones are examples and shell scripts. Convert the two AoE files to ReST format, and add the others as literal, as they're part of the documentation. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.
