Summary:
The reasoning behind this change is that right now, having both added and modified modules inside of a single `modules` field doesn't allow for basic operations like combining two deltas.
For instance, say I have three different bundle revisions: A, B and C.
Module 42 was added in B, and then removed in C.
A->B = `{modules: [42, "..."], deleted: []}`
B->C = `{modules: [], deleted: [42]}`
A->C = `{modules: [], deleted: []}`
However, were we to compute A->C as the combination of A->B and B->C, it would result in `{modules: [], deleted: [42]}` because we have no way of knowing that module 42 was only just added in B.
This means that the `deleted` field of delta X->Y might eventually contain module ids that were never present in revision X, because they were added and then removed between revisions X and Y.
The last time I changed the delta format, we had a few bug reports pop out from people who had desync issues between their version of React Native and their version of Metro. As such, I've tried to make this change backwards compatible in at least one direction (new RN, old Metro). However, this will still break if someone is using a newer version of Metro and an older version of RN. I created T37123645 to follow up on this.

Summary: Adds support for the `deleted` key to remove modules from the bundle. Without this, source maps would break after removing a module, since it would still end up in the patched bundle but not in the source map.

Summary:
Makes the delta bundle data structures more consistent.
The changes are as follows:
* There are now two types of JSON bundles that can be downloaded from the delta endpoint. Base bundles (`Bundle` type), and Delta bundles (`DeltaBundle` type).
* The `reset` boolean is renamed to `base`.
* `pre` and `post` properties are now strings.
* Only `Bundle` can define `pre` and `post` properties.
* The `delta` property is renamed to `modules`.
* Deleted modules are now listed inside of the `deleted` property, which is only defined by `DeltaBundle`.
