### _Why are the changes needed?_
We can detect engine dead cases after https://github.com/apache/incubator-kyuubi/pull/2122, so set thrift client socket timeout to inf to avoid socket timeout in blocking case, e.g. retrieve data except to 1st partition in increment collection mode, spark scale mode.
### _How was this patch tested?_
- [ ] Add some test cases that check the changes thoroughly including negative and positive cases if possible
- [ ] Add screenshots for manual tests if appropriate
- [x] [Run test](https://kyuubi.apache.org/docs/latest/develop_tools/testing.html#running-tests) locally before make a pull request
