[pve-devel] [PATCH storage] CephConfig: map special config key characters to _

[Dominik Csapak]

we want a consistent config has, regardless of how the user or a tool
adds it to the config, so we map ' ' and '-' to '_' in the keys

this way we can always access the correct key without trying multiple
times

i forgot to send this patch, it is necessary to get consistent
config accesses in our ceph stack
