[samuelmale]

Requirements

• This PR has a title that briefly describes the work done including the ticket number. If there is a ticket, make sure your PR title includes a conventional commit label. See existing PR titles for inspiration.
• My work conforms to the OpenMRS 3.0 Styleguide and design documentation.
• My work includes tests or is validated by existing tests.

Summary

This PR basically introduces support for capturing lab orders. The overwhelming consensus on how to capture orders in O3 is through the order basket, we are introducing this support to achieve parity with AFE.

Out of scope

I took the liberty of doing some housekeeping by introducing the EncounterFormManager which simply houses utils that facilitate encounter submission. This is a step forward towards simplifying the bloated EncounterForm component.

Potential improvements

• Auto focus to freshly replicated group when user clicks "Add"
• Prompt user with a confirmation modal upon deletion of a repeated row.
• Use formFieldPath to consistently reconstruct the orders tree
