Hello Lars Volker, Alexey Serbin, Dan Burkert, Kudu Jenkins,

I'd like you to reexamine a change. Please visit

    http://gerrit.cloudera.org:8080/9934

to look at the new patch set (#3).

Change subject: KUDU-2401: External TLS certificate with Intermediate CA in 
server cert file fails
......................................................................

KUDU-2401: External TLS certificate with Intermediate CA in server cert file 
fails

Take 2 certificate files: cert.pem and truststore.pem

cert.pem has 2 certificates in it:
A cert for that node (with CN="hostname", and signed by CN=CertToolkitIntCA)
And the intermediate CA cert (with CN=CertToolkitIntCA, and signed by 
CN=CertToolkitRootCA)

truststore.pem has 1 certificate in it:
A cert which is the root CA (with CN=CertToolkitRootCA, self-signed)

This previously would not work with KRPC because in
TlsContext::VerifyCertChainUnlocked(), we would only verify X509_verify_cert()
with the top certificate in the server certificate chain.

With this change, we pass the chain to X509_STORE_CTX_init() as well to make
sure that the entire chain gets checked against the CA.

A test is added that uses the specific certificate format mentioned above
and added to rpc-test.

TODO: Add a test case that has multiple intermediate CAs. Right now we're 
testing
with only one intermediate CA.
