Fix KeyPairProvider initialization in NetconfSshServerProvider

As a side offect of https://git.opendaylight.org/gerrit/#/c/60138,
RSA private key is stored unencrypted on disk.

Without additional countermeasures this might not be a good idea.

This patch sets DEFAULT_PRIVATE_KEY_PATH to null which disables
key pair serialization.
