Allow clients to disable auto-record feature (#530)

[hebdavepaul0]

PR for issue #530.

Adds a global boolean to control whether or not the framework will auto-record missing snapshots.

Helpful for cases where CI/CD might attempt multiple retries, and auto-recording snapshots could cause false successes.

I tested the suggested change locally and for me it works as expected.

If there is anything I can help with to get this merged (e.g. further testing), please let me know.

We need this functionality as well! I upvote this!

I was just testing this and it works well. I'm just thinking whether or not it makes sense to also include this as an argument to the assertSnapshot function, just as record is.

@stephencelis @mbrandonw do you think that makes sense?

Also, maybe this deserves a mention on the Readme, and we would probably need a bump? Unless maybe Brandon and Stephen take care of these once more PRs get merged?

This is useful to us to be able to disable recording missing snapshots on a per architecture basis:

#if arch(x86_64)
public var recordMissingSnapshots = false
#else
public var recordMissingSnapshots = true
#endif

Thanks for this! It would be really useful for us, for the same reason mentioned in the OP.

@stephencelis @mbrandonw will this still be considered? by the way, @hebdavepaul0 this has conflicts. 🙏🏼
