Delete organization by id endpoint

[8ivek]

User Story
We need an endpoint v1/organizations/:id which deletes an existing organization from the organization array.

We have an organizations array in server.js file

unitednepali/server/server.js

Line 5 in 50c12ac

const organizations = []

If you have any questions about this issue please slack in (#proj-unitednepali) or comment here.

endpoint: v1/organizations/:id
example: v1/organizations/1 (here 1 = id which gets deleted)
method: DELETE
input: none

response format:

{
	"success": 1,
	"timestamp": "2020-02-16T14:02-0400"
}

and the error format:

{
	"success": 0,
	"timestamp": "2020-02-16T14:02-0400",
	"error": "message"
}

note: you need to execute this using rest-client postman.

Acceptance Criteria
When querying v1/organizations (using GET method) from rest client (or browser) it should return all the organization as an array in JSON format but the deleted organization.

Test
Create a test (inside the cypress folder) and make sure the endpoint returns the expected response as above. Also, check if the record is deleted by querying organization/getall endpoint
