(PE-5859) Keep entire request URI matching regex

When wrap-proxy is called with a regex, keep the entire
portion of the request URI matching the regex rather than
replacing it in the rewritten URI.
(PE-5859) Address PR comments

Add a test where nothing is prepended to the proxied URI
when a regex is given to the wrap-proxy function. Add some
docs on the new behavior of the regex functionality. Bump
the version number to 0.2.0-SNAPSHOT for upcoming release.
(PE-5989) Change "prefix" to "path" in docs
(PE-5859) Strip trailing slash from remote uri

Strip the trailing slash from remote-uri-base so that repeat
slashes are not present when building the path of the
rewritten URI.
