Change default track (microovn, microcluster-token-distributor)

Hi,

Could you please change the default track for the microovn charm to 24.03 it is currently on latest, could you also change the default track for the microcluster-token-distributor charm to v1 as it is currently also on latest.

Thank you.

Hi @crypticcoder, done for both! Can take a look please? Thanks!
