Fixing CI build and removing Groovy.

Context

A new initial version of the library.

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.

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.

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)
);
