* Exit if loading an invalid identity from disk Previously, if an invalid identity was loaded from disk, ZeroTier would generate a new identity & chug along and generate a brand new identity as if nothing happened. When running in containers, this introduces the possibility for key matter loss; especially when running in containers where the identity files are mounted in the container read only. In this case, ZT will continue chugging along with a brand new identity with no possibility of recovering the private key. ZeroTier should exit upon loading of invalid identity.public/identity.secret #2056 * add validation test for #2056
