A small improvement on the compose-tracker tool

[Clement Verna]

Hi all,

I have made a small change to the compose-tracker [0] tool, which is a
fedora-messaging consumer creating tickets in this repo [1] for every
composes that does not complete successfully.

In each ticket you now have access to the time it took for the compose to
run, in addition with the details for each phases of the compose.

For an example look at the bottom of this ticket [2].

This is not much, but I think it helps making this information more
accessible.
