#942 Add POST /procedure/add method

This method adds a procedure associated with a center to the database.
Required payload parameters are center and name, description is
optional.

Note: ogServer does not allow to add more than one procedure with the
same name and center.

Request:
POST /procedure/add
{
  "center": "1"
  "name": "procedure1"
  "description": "My procedure"
}

Response:
200 OK

This commit also adds unit tests for /procedure/add POST method.
