Add support for more elasticsearch version as datasource

[rrey]

SUMMARY

In latest versions of Grafana, the elastic version is no more provided as an integer even if it is still supported and won't return any error. To ease configuration, the module will accept the version format as displayed by the WUI (ex: "7.10+") and will map the value to what the API expects ("7.10.0"). The added values are the one supported by Grafana 8 and 9 (greater than elastic 7.0 which was already supported).

The module will keep on supporting the old format to avoid a breaking change with significant impact. The integer format could be dropped when Grafana 10 would be released since the versions we support would be 8.x to 10.x that will all support the new format.
