NIFI-3788 Switched Amazon HTTP client instantiation from using null
HostnameVerifier (which defaulted to Strict, which cannot handle wildcard
certificate hostnames) to DefaultHostnameVerifier, which is fine.
I still want to add unit tests and integration tests, but I ran a flow which
had previously caused the reproducible exception and this worked fine (flow
showed objects were put in S3, no exceptions, and I verified through AWS Web
Console that new objects were present).
This closes #1753.

> Support wildcard certificates in SSLStandardContextService
> ----------------------------------------------------------
>
> Key: NIFI-3788
> URL: https://issues.apache.org/jira/browse/NIFI-3788
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core Framework
> Affects Versions: 1.1.1
> Reporter: Andy LoPresto
> Assignee: Andy LoPresto
> Labels: certificate, pki, security, tls
>
> Some users have reported issues when attempting to connect to an external
> service which is secured for TLS via a wildcard certificate (i.e. hostname is
> {{https://example.domain.com}} and the certificate DN contains
> {{CN=*.domain.com}}. This requires changes in the
> {{SSLStandardContextService}} to correctly parse the CN and evaluate wildcard
> entries if present.
> In addition, as specified by [RFC 2818|https://tools.ietf.org/html/rfc2818],
> certificate evaluation (specifically hostname validation) should prioritize
> Subject Alternative Names over DN parsing. Chrome 58+ has begun to implement
> this prioritization, which can cause issues with certificate validation even
> if the CN matches the hostname but SANs are present but do not include the
> hostname.
