[AndrewChubatiuk]

PR introduces VictoriaLogs datasource plugin for Perses. It has

• datasource plugin
• variable plugins: field names and field values

PR was heavily influenced by Prometheus and Loki plugins with API changes that are specific to VictoriaLogs

Not sure if UI screenshots are applicable here, since no custom styles are provided

depends on #392

Hey @AndrewChubatiuk,

Thank you for your PR. Can you add the plugin to the workspace list in the package.json at the root of the repo ? The CI will then be able to run and check the changes.

@abelyakin do you know if you will have time to provide the global LogTable panel. Just to know as we have another plugin coming from the community (thank you for that 🙏 ) that will provide his own LogTable and I guess that's the same than what is provided by Loki or ClickHouse

Hey @Nexucis, thanks for the heads-up. I’ll reserve some time next week to work on a separate LogTable panel 👍
