Support conventional server URL variable

[gabrielfeo]

As follow-up to #455 / #338, support the conventional server URL variable that's already set up for official Develocity tooling, such as

• any Gradle project using common-custom-user-data-gradle-plugin with a set Develocity URL override
• the Develocity Python agent

Config.apiUrl and DEVELOCITY_API_URL are renamed to Config.server and DEVELOCITY_URL for consistency with official Develocity tooling nomenclature.

Config.server is strongly typed as a URI and validation is improved.
