bump to hippo-cli 0.15
This makes spin compatible with Hippo v0.19.0.
closes #603
This now requires a bit of work to rebase (ref #681, cc @kate-goldenring).
@radu-matei and @vdice fixed the conflicts locally in my branch cherry-picking from @bacongobbler and then use GitHub UI to add the resolved file here. Should be good.
@kate-goldenring does the recently updated spin deploy logic need some fixups for hippo-0.19 compatibility?

Good point @vdice. Looks like I really merged these in the wrong order. I'll look into it.
Added in #697. Thanks!
