Verify peer cert function for better man in the middle prevention (#746)

Browse source 
* verify peer cert function for better man in the middle prevention

* publish cert chain hash generation algorithm

* added calculation of certificate hash as separate command and tlsping, use base64 to represent fingerprint to align with jsonPb

* apply coding style

* added test case for pinned certificates

* refactored cert pin

* pinned cert test

* added json loading of the PinnedPeerCertificateChainSha256

* removed tool to prepare for v5

* Add server cert pinning for Xtls

Change command "xray tls certChainHash" to xray style
