[snmp/agent] enable SNMP to create missing database directories
Add {db_init_error, create_db_and_dir} option to SNMP manager and agent. This allows them to create any missing parent directories for db_dir, rather than treating any missing directories as a fatal error. The default for db_init_error, which is terminate, is unchanged. Add create_db_and_dir to the documentation. Add new tests to verify that using create_db_and_dir results in missing parent directories being created.
