As a user, I can see the Test Set status based on test runs with the testset version, if available

The testset status column shown either in the issues list or in the testset tab, currently shows information of the tests belonging to the testset, considering the last run of the test, independently of in which version where it ran.

Since we may have several versions at the same time and we may be running the same tests on these different versions, the testset status should report information based on the test runs executed in the version indicated by the testset fix version;

A new configuration option should be available in the Xray configuration for configuring the strategy for the Test Set Status custom field. The user should choose one of two options:

• Earliest Unreleased Version: when this option is enabled, only the earliest unreleased Fix Version is displayed in the Custom Field.
• Earliest Unreleased Assigned Version: when this option is enabled, only the earliest unreleased Fix Version explicitly assigned to the Test Set is displayed in the Custom Field.
