nodepool: Add arm64ci cloud

Credentials are populated (Ib96d14008ab3b8b7c12429d7432eaa485c404bb2),
mirror.nrt1.arm64ci.openstack.org is alive so everything is ready to
go.

We have a quota of 40 cores & 96gb ram; the c1.large flavor is 8/core
8gb.  Should we should be able to fit 5 CI servers to start with.
