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

Other to do:

• Define the dialog for someone to set it up.
• Finish building the R functions
• Add function to collate the definitions data and R function to send that to the bucket
• Add in ability in R functions to takes the summary data frame created in our system (only focussed on the definitions so far)
• Add in functions which reformat from R-Instat to our style in the API
• Write a function which combines the "add_definitions_to_bucket" for the definitions along with the summary data frame so everything can be done in one line.

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.
