Introduce forceHttps flag in JsonSchemaFactory.Builder

[hisener]

In e32a541, schema normalization was introduced to fix #273 however it assumes the given schema is available over HTTPS.

json-schema-validator/src/main/java/com/networknt/schema/JsonSchemaFactory.java

Line 406 in e32a541

URI newUri = new URI("https", uri.getUserInfo(), uri.getHost(), uri.getPort(), uri.getPath(), null, null);

As reported in #314, some schemas are not available over HTTPS. For example, https://iglucentral.com (it just hangs with https), see snowplow/iglu-central#1067.

Therefore #314 blocks snowplow/iglu-scala-client#136 and our internal json-schema-validator dependency upgrade from 1.0.39 to 1.0.40+.

The first commit in this PR provides a failing test for #314 and the second one introduces a boolean flag to control the URI scheme.

Fixes #314.
