Provides information to other libraries in which environment they are running in.

Allows to set default properties for specific environments.

Typical use case is for various Wise libraries to set environment specific default properties in their `EnvironmentPostProcessor` implementations.

```java

WiseEnvironment.setDefaultProperty("my-library", WiseEnvironment.PRODUCTION, "tw-reliable-jdbc.sslMode", SslMode.VERIFY_FULL);

WiseEnvironment.setDefaultProperty("my-library", WiseEnvironment.STAGING, "tw-reliable-jdbc.sslMode", SslMode.PREFERRED);

WiseEnvironment.setDefaultProperty("my-library", WiseEnvironment.CUSTOM_ENVIRONMENT, "tw-reliable-jdbc.sslMode", SslMode.VERIFY_CA);

```

See `WiseEnvironment` class for other optional use cases. E.g. asking which environments are currently active.

The environments themselves can be hierarchical. In that sense, that if you set a default property to `STAGING`, it would also apply to

`CUSTOM_ENVIRONMENT`, unless a different value is specifically set for `CUSTOM_ENVIRONMENT`.

Also, a convenience DSL is available for setting properties. E.g.

```java

WiseEnvironment.setDefaultProperties(dsl -> dsl

    .source("tw-reliable-jdbc")

    .environment(WiseEnvironment.WISE)

    .set(TW_OBS_BASE_EXTREMUM_CONFIG_PATH, gaugeNames)

    .set("spring.flyway.validate-migration-naming", "true")

    .keyPrefix("tw-reliable-jdbc.")

    .environment(WiseEnvironment.PRODUCTION)

    .set("sslMode", SslMode.VERIFY_FULL)

    .set("requiredSslModeLevel", SslMode.VERIFY_CA)

    .set("requireMinPoolSizePct", 100d)

    .environment(WiseEnvironment.STAGING)

    .set("sslMode", SslMode.VERIFY_FULL)

);

```
