This is an internal package.
That means this is used as a dependency for other, public packages, but
should not be taken directly as a dependency in your application's package.json.
If you are updating the version of this package, for example to bring in a
bug-fix, you should do so by updating your application lockfile with
e.g. npm up @scope/package or equivalent command in another
package manager, rather than taking a direct dependency.
EndpointCache

the set operation stores milliseconds elapsed since the UNIX epoch in Expires param based on CachePeriodInMinutes provided in Endpoint.
the get operation returns all un-expired endpoints with their Expires values.
the getEndpoint operation returns a randomly selected un-expired endpoint.
