Trolli Schmittlauch 1fc264a226 manage logging via file handle

due to lazy evaluation is kept open multiple times.

Trolli Schmittlauch b23201a49c Make key lookups fail after request exhaustion instead of providing default

Especially for bootstrap joining this can be harmful, so signalling
instead that the lookup failed makes distinguishing on a case by case
basis possible.

Also contributes to #57
