Create new stats lambda function and context api for counts needed by the stats server

[acwhite211]

Create a lambda function and API Gateway on AWS that takes it stats data and edits a csv file for aggregated statistical data from all Specify 7 clients.

Edit the front-end code, in the systemInfo.ts file, to add a API request that sends the necessary stats data to the new lambda function endpoint. Also, edit the call to the Specify 7 back-end's context API with any new data fields.

Create a stats_counts api that returns in a json response the counts for collection objects, collections, and specify users. Incorporate this call to the context api with the front-end's call to the stats server. In the call to the stats server, add these new parameters.

@grantfitzsimmons I got a proof of concept working for the aggregated stats lambda function in the PR #7415 . Here are the current fields. We'll want to decide if there are any other fields we want to add.

institutionGUID
institution
version
dbVersion
disciplines
disciplineTypes
collections
collectionObjectCount
collectionCount
userCount
operatingSystems
browsers
ipAddresses
lastStatDateTime

Since a lot of that data is already captured by the existing stats server, we could just go with the new Count fields, and then any other new stats we want to add.

institution
collectionObjectCount
collectionCount
userCount
