KAFKA-19358: Updated share_consumer_test.py tests to use set_group_offset_reset_strategy (#19878)

According to the current code in AK, the offset reset strategy for share
groups was set using the flag `--offset-reset-strategy` in the
share_consumer_test.py tests, but that would mean that the admin client
call would be sent out by all members in the share group. This PR
changes that by introducing `set_group_offset_reset_strategy` method in
kafka.py, which runs the kafka-configs.sh script in one of the existing
docker containers, thereby changing the config only once.
