[FLINK-8080][metrics] Remove need for "metrics.reporters" config key
## What is the purpose of the change
This PR simplifies the reporter configuration by no longer requiring users
to explicitly set a list of reporter names via `metrics.reporters`. Instead,
the names are automatically determined based on
`metrics.reporter.<name>.<option>` keys found in the configuration.
## Brief change log
* modify reporter configuration parsing to detect reporter names
* deprecate `MetricOptions.REPORTERS_LIST`
* remove all usages
* remove all references from documentation
## Verifying this change
This change is already covered by existing tests in the various reporter
modules that configure a reporter.
See all tests where `MetricOptions.REPORTERS_LIST` was removed.
