fix: process.IPDatabase Errors, condition.IP Type

[jshlbrd]

Description

• Fixes an error in the IPDatabase processor that occurs when concurrency is enabled
• Refactors the IPDatabase Factory to follow our documented design pattern
• Adds new type check to IP inspector for checking if an IP address is any valid type
• Adds missing IPDatabase and DNS processor libsonnet configs from feat: DNS and IP Database Processing #39
• Adds new libsonnet pattern for looking up public IP addresses in IP enrichment databases

Motivation and Context

Discovered a bug in the IPDatabase processor when doing lower-level integration prep work -- if concurrency is active, then opening and accessing the database can randomly fail, but opening the database then putting it into the map fixes the problem.

While working on this I noticed two other things:

• the original PR for the IP database feature doesn't follow our design pattern for creating factories -- surprised I didn't catch this during development, the use of environment variables should have been a clue that something wasn't quite right with the solution
• the project has to support checking if an IP address is valid before sending it to the IPDatabase processor -- this processor may return an error indicating that the input is not a valid IP address, so we have to give users a way to handle that use case

How Has This Been Tested?

Generated a list of random IP addresses using IPVOID and tested different concurrency settings using the file app (SUBSTATION_CONCURRENCY=1, SUBSTATION_CONCURRENCY=2, SUBSTATION_CONCURRENCY=6). Unrelated to this change, using high concurrency settings (2+) when loading files from remote locations (HTTP) caused massive slowdown in runtime. We should encourage users to do local cacheing of files instead of pulling them from remote sources on every invocation, even if we don't provide tools to do the cacheing.
