HTTP Super SIDEBAND Requestor warnings on v11.6

These particular warnings are bogus and do not indicate bugs in the HTTP Super Sideband Requestor. BIG-IP TMOS has an iRUles (TCL) code validator which looks for symptoms of coding errors sometimes made by less experienced iRules developers (or accidentally added as typing mistakes by more-experienced coders!). Some of the things the validator flags are legitimate constructs that just happen to resemble common errors, in particular, "indirection" in assignments, like:

set a 0
set indirect_reference "a"
set $indirect_reference 1
log local0.info "after assignment, a = ${a}"

after assignment, a = 1

Indirection looks like the common error of putting a $ in front of the name of the destination variable in a set command, but intentional indirection is not an error. The validator cannot tell the difference so it issues a warning every time.

The warnings about \whatever are also bogus; the validator does not understand regular-expression syntax.
