IMPALA-13752: Remove option value quoting in __restore_query_options

Second run of test_parquet_late_materialization with codegen enabled
failed because ENABLED_RUNTIME_FILTER_TYPES option failed to restored
back to its default value, "BLOOM,MINMAX".

The root cause is the new collect_default_query_options() function in
impala_connection.py, added by IMPALA-13694. It will automatically wrap
list values in double quote. Consequently,
ImpalaTestSuite.__restore_query_options() does not need to wrap option
value with another single quote.

This patch also fix missing handling of optional query option without
any default value.

Testing:
Run the test with this command:
impala-py.test --exploration=exhaustive \
  -k test_parquet_late_materialization \
  query_test/test_parquet_late_materialization.py

> ImpalaTestSuite.run_test_case() reuse ImpalaConnection and restore its 
> configuration at the end of test via 
> ImpalaTestSuite.__restore_query_options(). We should make restoring query 
> options to default value generic inside ImpalaConnection. Currently, 
> ImpalaConnection has set_configuration, set_configuration_option, 
> get_default_configuration, and clear_configuration method, but there is no 
> reset_configuration method.
> Impala py.test code should also consistently lower case query options names 
> everywhere, following standard set by IMPALA-13319.
