[pve-devel] [PATCH manager v2 4/5] fix #4497: cli/acme: detect eab and ask for credentials

[Folke Gleumes <f.gleumes@proxmox.com>]

Since external account binding is advertised the same way as the ToS,
it can be detected when creating an account and asked for if needed.

Signed-off-by: Folke Gleumes <f.gleumes@proxmox.com>

Changes v1 -> v2:
 * If a custom directory is used, ask if EAB should be used, even when not required by the CA.
