Dry Release v0.2

[maxceem]

Together with merging this PR we have to run migrations:

• Run npm run migrate - it would apply all the migrations at once.
  Prior to running this script we have set the next env variables for DB connection:

  DB_USERNAME
  DB_PASSWORD
  DB_NAME
  DB_HOST
  

• Run the next SQL commands manually:

   ALTER TABLE bookings.jobs ADD COLUMN "workload" character varying(45);
   UPDATE bookings.jobs SET "workload"='full-time' WHERE "workload" is NULL;

We also have to update ES mapping for all the changes. So we have to run several PUT requests:

1. PUT /job/_mapping
   {
    "properties": {
      "title": {
         "type": "text"
      }
    }
   }
   

2.  PUT /job_candidate/_mapping
    {
      "properties": {
         "resume": {
           "type": "text"
         },
         "externalId": {
           "type": "keyword"
         }
       }
    }
   

3.    PUT /job/_mapping
       {
          "properties": {
          "workload": {
             "type": "keyword"
           }
        }
      }
