TTP Lazy importing system modified to use pickle module to cache ttp dictionary and to scan subfolders' files one by one,
that is to avoid "OSError: [Errno 24] Too many open files" problem when TTP scans through folders to find all function;
additionally, added caching functions to speed up initialization process roughly by 60ms.
Output traverse function added "strict=True" boolean parameter, if True - traverse raises KeyError if no path item found
in results, if False, will return empty dictionary if no item found in results
Improved Syslog returner - wrapped sending logs to try-except blocks with logging of errors on failure
Improved results path selection to use group.group_id instead of path and index attributes
Generalized anonymous group name, path and group_id formation to account for nested/child anonymous groups
Modified yangson validate behavior to return error if no yangson installed, added option to just return results without metadata if validation was successful
