Comment 9 for bug 1886630

Subscribing ~field-high again. I've realized that the cipher change hasn't been applied to reactive charms as a part of 20.08, then found charm-layer-openstack has to be updated too.

I'm aware a similar escalation has been done as bug 1892450, but I'm focusing to propagating the original charm-helper change to all OpenStack API charms here. Please review and merge the change when appropriate, and backport it to 20.08. At this moment, inconsistent cipher list is used between classic vs reactive OpenStack charms.
