Would like OPT_SEEK_FACTOR as a session set environment option

In 11.70, a new "seek cost" component for index costing was introduced, the purpose of which was to more accurately reflect the cost for seeking in an index scan (when index is not clustered) for large indexes.

OPT_SEEK_FACTOR is an undocumented ONCONFIG parameter that can be used to adjust the effect of this new seek component on the index scan costing. It's an integer that can be set to a value between 0 and 25, with a default setting of 6. If it's set to 0, then no seek component is added, which is the same as the costing would be in 11.50.

The DBA would like to test the impact of the OPT_SEEK_FACTOR on selected queries by setting a session environment variable instead of setting OPT_SEEK_FACTOR for the entire instance and have it affect all the queries on the production instance.
