## What has been done here
In a nutshell on a field metadata type ( `SELECT MULTI_SELECT` ) update,
we will be browsing all `ViewFilters` in a post hook searching for some
referencing related updated `fieldMetadata` select. In order to update
or delete the `viewFilter` depending on the associated mutations.
## How to test:
- Add FieldMetadata `SELECT | MULTI_SELECT` to an existing or a new
`objectMetadata`
- Create a filtered view on created `fieldMetadata` with any options you
would like
- Remove some options ( in the best of the world some that are selected
by the filter ) from the `fieldMetadata` settings page
- Go back to the filtered view, removed or updated options should have
been hydrated in the `displayValue` and the filtered data should make
sense
## All filtered options are deleted edge case
If an update implies that a viewFilter does not have any existing
related options anymore, then we remove the viewFilter
## Testing
```sh
PASS test/integration/metadata/suites/field-metadata/update-one-field-metadata-related-record.integration-spec.ts (27 s)
update-one-field-metadata-related-record
SELECT
✓ should delete related view filter if all select field options got deleted (2799 ms)
✓ should update related multi selected options view filter (1244 ms)
✓ should update related solo selected option view filter (1235 ms)
✓ should handle partial deletion of selected options in view filter (1210 ms)
✓ should handle reordering of options while maintaining view filter values (1487 ms)
✓ should handle no changes update of options while maintaining existing view filter values (1174 ms)
✓ should handle adding new options while maintaining existing view filter (1174 ms)
✓ should update display value with options label if less than 3 options are selected (1249 ms)
✓ should throw error if view filter value is not a stringified JSON array (1300 ms)
MULTI_SELECT
✓ should delete related view filter if all select field options got deleted (1127 ms)
✓ should update related multi selected options view filter (1215 ms)
✓ should update related solo selected option view filter (1404 ms)
✓ should handle partial deletion of selected options in view filter (1936 ms)
✓ should handle reordering of options while maintaining view filter values (1261 ms)
✓ should handle no changes update of options while maintaining existing view filter values (1831 ms)
✓ should handle adding new options while maintaining existing view filter (1610 ms)
✓ should update display value with options label if less than 3 options are selected (1889 ms)
✓ should throw error if view filter value is not a stringified JSON array (1365 ms)

## Out of scope
- We should handle ViewFilter validation when extracting its definition
from the metadata
https://github.com/twentyhq/core-team-issues/issues/1009
## Concerns
- Are we able through the api to update an RATING fieldMetadata ? ( if
yes than that's an issue and we should handle RATING the same way than
for SELECT and MULTI_SELECT )
- It's not possible to group a view from a MULTI_SELECT field
The above points create a double nor a triple "lecture" to the post hook
effect:
- ViewGroup -> only SELECT
- VIewFilter -> only SELECT || MULTI_SELECT
- Rating nothing
I think we should determine the scope of all of that
