The dns_nederhost DNS API relies on the exact HTTP status code to be
returned (e.g. 204); however, the _get function always returns 200 for a
succesful call when using wget instead of curl. This patch fixes this by
using the _post function for all requests done by dns_nederhost.
The function '_get_root' tries to retrieve the
hostedzone iterating the domains, eg:
1. srv.prod.example.com
2. prod.example.com
3. example.com
This doesn't work if '_acme-challenge' is in it's
own hostedzone for security reasons.
Starting that iteration with '_acme-challenge.srv.prod.example.com'
fixes this issue.
When performing renewals acme.sh checks key length values to determine
if a new key should be created with createDomainKey(). However, older
acme.sh stored key length as an empty value if the default of 2048 was
desired. Now it is explicit and the explict check of 2048 against "" is
causing createDomainKey() to always be called with fails without
--force.
Fix this by converting the keylength value to 2048 if an empty string is
returned from the config file. acme.sh will then write out 2048 updating
old keys and configs to the explicit version.

- Now note the ID in (...) from the edit page behind "_acme-challenge.example.com"
