Excavator: Manage go module dependencies (#135)

Add new batch modes (#133)

batch-serial is back-compat with serial, and batch-canary with canary,
but added as new commands for now to ensure not to disrupt workflows
relying on these commands to be bulletproof

Bump retries & fix context timeouts (#131)

* Bump built-in retries to 20

Default is 3, with a max back-off time of 20s between attempts

https://aws.github.io/aws-sdk-go-v2/docs/configuring-sdk/retries-timeouts/#standard-retryer

* NewContext should actually be new

It shouldn't be based on the previous context, and therefore inherit its deadline and just try to implement an additional one - this will never work because the old deadline will always be the initial timeout time after launch, and we aren't actually renewing a timer at all. By just creating a brand new context every time instead and throwing the old one away, we're actually getting a fresh timer.

* remove double-sleep

Switch to AWS SDK v2 (#127)

* Switch to AWS SDK v2

As per https://pkg.go.dev/github.com/aws/aws-sdk-go-v2/aws/retry#hdr-Standard , one of this SDKs improvements should be automatic retry in the case of throttling limit errors

* small fixes

* fix some pointer handling

* Pass-around TODO contexts correctly

* Always call cancel on failure

* Take a stab at using contexts for timeouts

Rather than using the self-implemented timeouts at all

* exported function

* small cleanups

* Use logrus exit handler

Support jq 1.5 (#125)
