Disable interpolation of Asciidoctor for the path part of the Rest Enpoint (#327)

* Disable interpolation of Asciidoctor for the path part of the Rest Endpoint

Previously, when generating Asciidoctor snipppets, based on this template, the path parameter was interpolated.
This was considered by Asciidoctor as an attributes which are typically surrounded by { and }. 

This commit surrounds the path with + characters which disables all interpolation.

Closes #326

* Review unit test after having surrounded the content of 'default-auto-method-path.snippet' with a '+' to avoid interpolating path variables

Closes #326
