Is your feature request related to a problem? Please describe.
Although these are in the custom section and may need adjustment depending on resolution of the hogging task related issues, the current implementation is missing associated requirements for HS_REPORT_DIAG_CC, HS_SET_UTIL_PARAMS_CC, HS_SET_UTIL_DIAG_CC:

HS/fsw/src/hs_custom.h

Line 71 in 8ce4dd7

#define HS_REPORT_DIAG_CC 12

HS/fsw/src/hs_custom.h

Line 98 in 8ce4dd7

#define HS_SET_UTIL_PARAMS_CC 13

HS/fsw/src/hs_custom.h

Line 124 in 8ce4dd7

#define HS_SET_UTIL_DIAG_CC 14

Describe the solution you'd like
All commands should have associated requirements, add.

Describe alternatives you've considered
None in the short term. Longer term may update behavior based on:

• HS Telemetry reporting per-core CPU utilization on SMP #3
• HS idle task consumes 100% CPU on POSIX systems #4

Additional context
Really should be at minimum in the draco-rc2 requirements documents (as well as many historical versions).
