The send-pack --force-with-lease option populates a push_cas_option
struct with allocated strings. Exiting without cleaning this up will
cause leak-checkers to complain.
We can fix this by calling clear_cas_option(), after making it publicly
available. Previously it was used only for resetting the list when we
saw --no-force-with-lease.
The git-push command has the same "leak", though in this case it won't
trigger a leak-checker since it stores the push_cas_option struct as a
global rather than on the stack (and is thus reachable even after main()
exits). I've added cleanup for it here anyway, though, as
future-proofing.
The leak is triggered by t5541 (it tests --force-with-lease over http,
which requires a separate send-pack process under the hood), but we
can't mark it as leak-free yet.
