WebUI: Add Adapter for certmap_match result table

Result of certmap_match command is in the following format:
[{domain: 'domain1', uid:[uid11,uid12,uid13]}, {domain: 'domain2',
uid:[uid21, uid22, uid23},...]

For correct displaying in table we need to reformat it to the following:
[{domain: 'domain1', uid: 'uid11'}, {domain: 'domain1', uid: 'uid12'},...

This can be done using this Adapter.
