Support Connector name in SQL identifiers

[mediuminvader]

Is your feature request related to a problem? Please describe. In case of connectors are ingesting data from different tables with the same name, a naming convention in SQL is necessary to identify the table or the field to use.

Describe the solution you'd like Allow to specify a table identifier like connection_name.table_name and a field identifier like connection_name.table_name.field_name
