to enable the customization the env variable ENABLED_CONNECTOR_EMBEDDING_SETTINGS must be true
the fields embedding and chunk overlap were added to ConnectorForm and are listed in the ConnectorTable
the table connector was modified to add embedding and chunk columns, and the current connectors will be modified to assign values to those columns, 500 -> embedding / chunk->0
modify all places where the constants DOC_EMBEDDING_CONTEXT_SIZE and DOC_EMBEDDING_CONTEXT_SIZE where used to get those values from the column connectors
