Context:
As more and more public APIs are added we decide to consolidate the accessToken(s) together into one shared config, see https://camunda.slack.com/archives/CNSMT82SJ/p1639386771001800
AT:
- a global accesstoken config is used by all public APIs of Optimize, see https://docs.camunda.org/optimize/develop/technical-guide/rest-api/
- there is already an existing config property to be used being api.optimizeAccessToken
- the following accessToken configs are removed from the documentation:
- eventBasedProcess.eventIngestion.accessToken
- externalVariable.variableIngestion.accessToken
- export.json.accessToken
- the following accessToken configs are marked as deprecated:
- eventBasedProcess.eventIngestion.accessToken
- externalVariable.variableIngestion.accessToken
- there is no automatic access token generation in case the value is set to `null` but instead api calls will be blocked (as already done for export.json.accessToken
- the documentation is adjusted accordingly
