Solution to issue 15

[m-tarhon]

I have added a way for the plugin backend to be prepared to test any type of input for the time-series time field that it gets, and convert it to the proper type - time.Time - that the backend expects.

Summary of Changes

Hello @m-tarhon, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly improves the Couchbase Grafana plugin's ability to process time-series data by introducing flexible parsing for time fields. It ensures that regardless of whether the time data is provided as an RFC3339 string, epoch milliseconds (as string, float, or integer), the backend correctly converts it to a time.Time object, enhancing data consistency and reliability.

Highlights

• Enhanced Time Field Handling: The plugin backend now robustly handles various input formats for time-series time fields, including RFC3339 strings, epoch milliseconds as strings, float64, and int64, converting them all to time.Time objects.
• Issue #15 Resolution: This change directly addresses and resolves the issue #15, which highlighted the need for broader support for different time field formats.

Code Review

The pull request introduces enhanced time-series data handling for the plugin backend, specifically addressing issue #15. The changes involve adapting the system to accept and convert various input types for the time field into the time.Time format expected by the backend. This includes handling string, float64, int64, and time.Time types, parsing RFC3339 strings, and converting epoch milliseconds. I have identified a potential issue with error handling in the normalizeFieldData function, where a panic is raised for unsupported time field types. I suggest considering a more graceful error handling approach to prevent application crashes.
