Alex Hall	4408315f2e	(core) Add AzureExternalStorage ... Summary: Adds a new implementation of the interface ExternalStorage that works for Azure Blob Storage as an alternative to S3, for a specific self-hosting case. Tweaks HostedStorageManager and ICreate to allow configuring different core implementations of ExternalStorage. Followup tasks: - Make this code available to self hosters, possibly by making it open source. - Add an env var or other config option to specify the preferred type of storage. Currently using the var `AZURE_STORAGE_CONNECTION_STRING` to know how to connect to Azure when requested, but that choice still only lives in test code. Test Plan: Generalized HostedStorageManager and ExternalStorage tests to test the new AzureExternalStorage alongside S3ExternalStorage. The HostedStorageManager tests also now test the 'cached' in-memory test storage in a way that's closer to the real storage methods.

Paul Fitzpatrick	71519d9e5c	(core) revamp snapshot inventory ... Summary: Deliberate changes: * save snapshots to s3 prior to migrations. * label migration snapshots in s3 metadata. * avoid pruning migration snapshots for a month. Opportunistic changes: * Associate document timezone with snapshots, so pruning can respect timezones. * Associate actionHash/Num with snapshots. * Record time of last change in snapshots (rather than just s3 upload time, which could be a while later). This ended up being a biggish change, because there was nowhere ideal to put tags (list of possibilities in diff).
