Annotation support for temporary password and encrypted secrets

[credmond-git]

Currently to setup a temporary password or an encrypted password you need to use a builder.
For example:

Map<String, String> configs = new HashMap<>();
configs.put("my.password", "abcdef");

GestaltBuilder builder = new GestaltBuilder();
Gestalt gestalt = builder
  .addSource(MapConfigSourceBuilder.builder()
    .setCustomConfig(configs)
    .build())
  .addTemporaryNodeAccessCount("password", 1)
  .build();

Annotation support for temporary password and encrypted secrets

configs.put("my.password", "abcdef@{temporary:4}");

configs.put("my.password", "abcdef@{encrypt}");

The annotation will be removed from the configuration.
So after processing it would look like my.password ="abcdef"

For this to work, with the no cache feature, leaf nodes need to support metadata. Then we add a metadata to not cache the result. We then need to pass up the metadata with a decoded value.

So internally we would wrap all results in a container config object that returns the decoded value with any meta data.
For complex types like classes and records, the meta data will contain all the meta data of the leaf nodes.
