[ACTION] Upsert Records into Salesforce

[daniel-adayev-prefect]

[Is there a specific app this action is for?

Please provide a link to the relevant API docs for the specific service / operation.](https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/dome_upsert.htm)

Upsert functionality would greatly reduce compute and time required having to check if records exist in our system before pushing them in.

@vunguyenhung not any field can be used as the external ID field, I tested this and the API returns an error. Therefore, only fields that are actually marked as an external id field can be used, and the prop filters to show only those.

A field can be created in the Salesforce interface in Object Manager, and marked as an external ID field.

I've added an info prop to the component with a brief description regarding this.
