When configuration path is used and QuickBuild is running behind apache, the REST API for fetching changes and issues cannot work correctly.

We'd like to change all params for configuration path from
PATH:root/abc/def
to simply
root/abc/def
no any prefix PATH: and needn't escape the param.

For example, in old version, to fetch the stats of changes for configuration root/abc/def, we will use:
/rest/changes/stats/PATH:root%2Fabc%2Fdef
here, %2F is escaped code for slash /,

in new version, we will simply use:
/rest/changes/stats/root/abc/def

if you are using configuration id instead of configuration path, it doesn't impact.
