Add support for disabled reason with utPLSQL v3.1.12

[jgebal]

With utPSLQL v3.1.12 we will allow users to provide reason when test is disabled.
See PR 1183
The disabled reason should be consumed by IDE and shown in test results window of utPLSQL.

There is an issue open in PLSQLDeveloper plugin to address the same.
utPLSQL/utPLSQL-PLSQL-Developer#25

@simasch @PhilippSalvisberg @lwasylow
Let's discuss the details of implementation there.

The ut_realtime_reporter in utPLSQL v3.1.12 does not include the disabled reason. Hence it is currently not possible to show that in the UI. Maybe with v3.1.13.
