Serialise drctl boolean flags with the "=" form

[delthas]

What does this PR do, and why do we need it?

CTST built every zenko-drctl command line with --flag value. pflag boolean flags do
not consume the next argument, so --force-rotate-service-credentials false set the flag
to true and left "false" as a positional argument, silently ignored.

Every Given a DR installed therefore force-rotated the sink's service credentials,
instead of only the install that follows an uninstall. Each rotation rolls the sink's
backbeat pods and can stall D/R replication, which shows up as intermittent PRA failures:
on run 34585935213 the six
installs produced six rotations on the sink against one on the source, and both failing
scenarios were replicated deletes that never landed.

Emit booleans as --flag=value, and cover paramToCli in the tests for
common/utils.ts, renamed from parseGoDuration.test.ts now that it holds cases for a
second helper.

Which issue does this PR fix?

Fixes ZENKO-5356.
