Responses from metadata service are not trimmed before parsing. They rely on underspecified behaviour of the metadata service api.
Before parsing the response, we should at least trim any excessive whitespace
If the response contains any whitespace (like a newline at the end of it), the parsing of some of the fields fails.
This applies to InstanceID(), PublicIPv4().
InstanceID()
PublicIPv4()
In addition, the return values of all other functions would also include the additional whitespace, leading to unexpected results downstream.
