See comment in OPT-4274 (https://jira.camunda.com/browse/OPT-4274?focusedCommentId=159435&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-159435).

To be consistent with engine telemetry, we should add "raw" license key data as well as ensure to consistently use hyphens for all telemetry fields that are more than one word (eg licenseKey, engineInstallationIds, validUntil etc).

AT:

• Add "raw" license key to license key telemetry
• Also use hyphen instead of camelcase for other fields that are more than one word
• Update documentation https://docs.camunda.org/optimize/develop/technical-guide/setup/telemetry/ and https://confluence.camunda.com/display/CO/Optimize+Telemetry
