Since we switched to using the cobra command context instead of
`appcontext`, we need to set up the signal handling that was being
provided by `appcontext`, as well as configuring the context with
the OTEL tracing utilities also used by `appcontext`.
This commit introduces `cobrautil.ConfigureContext` which implements
the pre-existing signal handling logic from `appcontext` and cancels
the command's context when a signal is received, as well as doing
the relevant OTEL config.

The --builder flag was being ignored by imagetools because of pointer
problems. Essentially, because the root cmds aren't parsed immediately,
we need to pass a pointer to the builder string so that it can be
updated before the RunE function gets called.
