Adding ssl config params to Postgres URI (#6580)

* use pg-promise native pg-connection-string to parse uri instead of ParseConfigParser.js. The allows for a more felxible uri for ssl and other params

* added ssl config params and others to PostgresConfigParser

* forgot to add back the original client file

* need to read in file at path for pfx, ca, key, and key

* convert file buffer to string to be consistant with node-postgres examples
