Consider retiring covidcast-csv-server

[sgratzl]

https://github.com/cmu-delphi/covidcast-csv-server was used to convert covidcast signal into a CSV format.

e.g.:
https://delphi.cmu.edu/csv?signal=doctor-visits%3Asmoothed_adj_cli&start_day=2021-04-06&end_day=2021-05-04&geo_type=county

which results in
covidcast-doctor-visits-smoothed_adj_cli-2021-04-06-to-2021-05-04.csv

the new covidcast api has a similar endpoint:

https://delphi.cmu.edu/epidata/covidcast/csv?signal=doctor-visits%3Asmoothed_adj_cli&start_day=2021-04-06&end_day=2021-05-04&geo_type=county

covidcast-doctor-visits-smoothed_adj_cli-2021-04-06-to-2021-05-04 (1).csv

from what I see the differences are:

• sorted -> will be fixed soon
• that the id resets itself after a while -> I assume a batching artifact?

Thus we could retire the CSV project and add a forward from /csv to /epidata/covidcast/csv for backwards compatibility.
