Nowadays, when trying to update node config in case of read-only storage file
we have non-information error
{code:java}
java.nio.file.FileSystemException: /opt/gridgain/etc/gridgain-config.conf.tmp
-> /opt/gridgain/etc/gridgain-config.conf: Device or resource busy

org.apache.ignite.internal.configuration.storage.LocalFileConfigurationStorage.mergeAndSave(LocalFileConfigurationStorage.java:245)

So, we need to create better description and returns it with correct error code
in REST
