Function to upload definitions and summaries from R-Instat to Buckets

[lilyclements]

To do to upload the definitions and summaries from R-Instat into buckets:

1. Define the dialog for someone to set it up.
2. Build the R function that takes the summary data frame created in our system with the calculation system, and produce an output with the data frame table and json definitions
3. Write a function which takes the jsons definitions and the summary data frame and uploads them

TODO Write file to get definitions from R-Instat into json for

In epicsadata the definitions are now done for all summaries in the annual_rainfall - except for seasonal_n_rainy_days.

In epicsadata the definitions are now done for annual/monthly temperature summaries

I've written up in the "Discussions" on testing this and exploring this.
