IMPALA-5736: Add impala-shell argument to set default query options
Query options can be set from command line and impala rc as
key=value pairs, where key is case insensitive.
Examples:
command line:
impala-shell.sh -Q MT_DOP=1 --query_option=MAX_ERRORS=200
.impalarc:
[impala.query_options]
EXPLAIN_LEVEL=2
MT_DOP=2
The options set in command line will update the ones
in impalarc one by one, so the result of the example
above will be:
EXPLAIN_LEVEL=2
MT_DOP=1
MAX_ERRORS=200
Additional changes:
- 0 and 1 are accepted as bools in section [impala] to
make it more consistent with [impala.query_options]
- options that are expected to be bool but are not
0/1/true/false lead to error instead of warning
