[kolla] PTL on holiday next week

Hi, I'll be on holiday next week. Please keep in mind the current feature freeze and aim for stabilisation of the code and preparation for RC1 & branching. Let's aim to branch in the week beginning 19th April. Please also remember it's the PTG in the same week. Remember to add topics to the PTG Etherpad [1] as they come up in discussion or your thoughts. [1] https://etherpad.opendev.org/p/kolla-xena-ptg Thanks, Mark
