adding an initializer preventing create partition statements from get… (#5737)

…ting into structure.sql

**Story card:**
[sc-17444](https://app.shortcut.com/simpledotorg/story/17444/exclude-reporting-patient-states-partitions-from-appearing-into-structure-sql)

## Because

We have a partitioned table reporting_patient_states.
Every time we do a reporting refresh, partitions gets created
dynamically on this table (if they don't already exist).
These partitions appear on structure.sql as well with something like
CREATE TABLE simple_reporting.reporting_patient_states_20180101 (

These create partition statements are not really needed in structure.sql
because

These partitions are created dynamically through the rake task, if one
doesn't exist
Having a create statement for each partition makes the file very messy
and unnecessarily long.
We need to get rid of these create statements from getting into the
file.

## This addresses

Adding an initializer which has 'exclude-table' param to ignore these
partition create statements from appearing into dump

## Test instructions

Run rake db:refresh_reporting_views - this will create some partitions
on reporting_patient_states
Run rails db:migrate
Verify structure.sql, create with individual partitions should not be a
part of it.
