Summary

Currently running a disruptive detail does nothing even when --disruptive flag was specified due to the requested detail e.g psu(disruptive) not matching any handler in DETAIL_FUNCTIONS.

[root@vpr414 admin]# showtech --details "psu(disruptive)" --disruptive
I0115 16:28:20.640184  6834 PlatformNameLib.cpp:80] Platform name read from cache: MERU800BIA
[root@vpr414 admin]#

We need to trim "(disruptive)" suffix from detail string before looking up the appropriate handler in DETAIL_FUNCTIONS.

Test Plan

Running a disruptive detail calls the appropriate handler

[root@vpr414 admin]# showtech --details "psu(disruptive)" --disruptive

Running a disruptive detail without --disruptive is guarded
