[TASK] Add support for passing certificates to server_ctt

 - Added command line argument to pass trusted certificate
   and CRL files
 - Copy all certificates to open62541\build\bin\examples\trustList
 - Copy all revocation list to open62541\build\bin\examples\crl
 - usage : ./server_ctt server_cert.der server_key.der
           <number of certificates>
           <number of revocation files> trustList/* crl/*
