> Authz APIs introduced in RANGER-5309 support name of the accessed resource to be provided as a string, instead of a map used in plugin APIs. For example:
>  * a column:
>  ** Authz APIs: {{column:db1.tbl1.col1}}
>  ** plugin APIs: {{{ "database": "db1", "table": "tbl1", "column": "col1" }}}
>  * an ozone key:
>  ** Authz APIs: {{key:vol1.bucket1/p1/p2/file.txt}}
>  ** plugin APIs: {{{ "volume": "vol1", "bucket": "bucket1", "key": "p1/p2/file.txt" }}}
> The string format is easier to read than the map format, and will result in smaller payloads as well. However, the parsing introduced in RANGER-5309 supported more complex constructs like: prefix, suffix, different separators between resources. These are unnecessary, given the need is to capture hierarchy of resources. Hence, I propose to simplify the resource name format to:
>  * remove support for prefix and suffix in resource names
>  ** {{key:ofs://vol1/bucket1/p1/p2/file.txt}} will not be supported; this resource should be specified as {{key:vol1/bucket1/p1/p2/file.txt}}
>  * use only "/" as the separator, with option to escape using backslash (\)
>  ** {{relativepath:container1@account1/p1/p2/file.txt}} will not be supported; this resource should be specified as {{relativepath:account1/container/p1/p2/file.txt}}
