Include instructions or script for updating table definition

[ibarra-michelle]

Consider adding instructions or adding a script for updating the table definition so it continues working for our Docker workflow and cg db. Below are draft steps on how to do the manual update:

1. ssh to DB
2. Drop table
3. CREATE TABLE with .sql
4. Save csv in local Postgres bin folder (temp solution until we can point to repo with csv)
5. Copy data from csv:
   \COPY UNIT_UNIVERSE FROM 'Y2017-2019 unit-universe-data.csv' DELIMITER ',' CSV HEADER;
