disable callbackWaitsForEmptyEventLoop

[bluedusk]

Disable callbackWaitsForEmptyEventLoop for HTTP OPTIONS request since ApolloServer already disable callbackWaitsForEmptyEventLoop for POST request. (

apollo-server/packages/apollo-server-lambda/src/lambdaApollo.ts

Line 33 in 1ec2890

context.callbackWaitsForEmptyEventLoop = false;

)

Otherwise is lambda event loop is not empty, subsequence HTTP OPTIONS request will be hang and even timeout without throwing proper error.
