We now remove null-valued properties when transforming properties to their PropertySource representation. Vault can reply with null-valued properties that causes NullPointerException with the ConcurrentHashMap implementations.
Closes gh-69.
Replace static imports with qualified use. Add author tags. Add copyright header. Simplify code. Simplify JavaDoc documentation. Rename test class and methods to align with project style.

We now accept TaskScheduler in LifecycleAwareSessionManager to schedule session refresh tasks. Previously, LifecycleAwareSessionManager used AsyncTaskExecutor with Thread.sleep(…) to delay execution. Thread.sleep blocks a thread exclusively which is an inefficient resource usage.
Closes gh-59.
We now provide a Lease-aware PropertySource to renew and rotate secrets requested by that PropertySource. Lease renewal is applied per property source to control individual secrets with individual lease durations. A terminal expired lease can be either rotated to obtain new credentials. A non-rotated secret that terminally expires is removed from the property source. LeaseAwareVaultPropertySource is updated by SecretLeaseContainer on a background thread.
Components created with properties retrieved from LeaseAwareVaultPropertySource are not refreshed upon secret rotation.
@VaultPropertySource(value = "aws/creds/s3", renewal = Renewal.ROTATE)
public class Config {
}
@VaultPropertySource(value = "mysql/creds/my-role", renewal = Renewal.RENEW)
public class Config {
}
Closes gh-50.
Provide a EnvironmentVaultConfiguration for common configuration scenarios to obtain configuration from Spring's Environment. EnvironmentVaultConfiguration supports various authentication mechanisms: Token, AppId, AppRole, AWS EC2, Client-Certificates, and Cubbyhole.
Java-based configuration class:
@PropertySource("vault.properties")
@Import(EnvironmentVaultConfiguration.class)
public class MyConfiguration{
}
vault.properties
vault.uri=https://localhost:8200
vault.token=…
Closes gh-30.
VaultClients.createRestTemplate() creates a RestTemplate that is configured with ByteArray, String and Jackson 2 message converters to avoid additional message converters to be registered, if they were on available on the classpath.
Fixes gh-47.
Provide VaultTransitContext.empty() to create an empty VaultTransitContext for encryption/decryption of binary plaintext without requiring to use VaultTransitContext builder.
Closes gh-54.
Remove VaultClient from VaultTemplate and switch implementations to use RestOperations directly. VaultClient provided an additional abstraction level over RestTemplate with a large API surface adding only little value.
Implementations work directly with RestOperations. Relative URI expansion is handled by DefaultUriTemplateHandler configured with the VaultEndpoint base URI.
Closes gh-49.

We now support optional prefixing of property names. Property names coming from Vault are exposed with a prefixed name through VaultPropertySource.
@VaultPropertySource(value = "mysql/creds/readonly", propertyNamePrefix = "database.")
static class Configuration{}
will expose all keys under "mysql/creds/readonly" prefixed with "database." that lead properties known as "database.username" and "database.password".
Closes gh-48.
