Batch concurrent requests serially

[kmcginnes]

Description

In a few cases we can not avoid sending many parallel requests to the server. Since some servers implement throttling, we want to batch up those requests in to smaller groups and execute them in serial.

• Update openCypher keyword search query template
  • Fix limit and offset
  • Add ability to handle multiple vertex types in a single request
  • Sort by ID
  • Better formatting of strings
• Consolidate multiple openCypher search requests in to a single request
• Add batchPromisesSerially() function to manage the batching logic
• Batch all the Promise.all() occurrences in the code
• Default concurrent request batch size is set to 10

Validation

• Tested openCypher search
• Tested openCypher schema sync
• Tested sparql schema sync
