Opencensus postgres plugin issue in client path

[anujkalka]

Opencensus postgres plugin, located at src/census/plugins/pg.ts has incorrect path to client. The variable which describes the version and client path internalFileList = { '7.x': { 'client': 'client' } } describes client to be present at location 'client'. But in version 7 client file is located at location 'lib/client' As a result pg transaction tracking not working even in simple application

Fix: Changing path to lib/client would fix this problem.

UPDATE -- To support pg client 6 and 7,, need to update the same code as internalFileList = { '6 - 7': { 'client': 'lib/client' } }
