apollo-server-plugin-base depends on apollo-server-core but doesn't include it as a dependency

As it was discovered here:

yarnpkg/berry#271 (comment)

I see in package.json apollo-server-core is a dev dependency. is this a bug or was it intended?

Left a comment on the attached issue. In short: it's a dev dependency because it only uses the typings, but I'm not sure what the appropriate way to express that is.

The primary reason we don't want to make apollo-server-plugin-base have a regular (vs. dev) dependency on the apollo-server-core package is to maintain separation between the apollo-server-plugin-base package and specific versions of apollo-server-core (and other integrations), in order to allow plugins to evolve at their own rate while still being compatible at least the major version of Apollo Server.

This may be, yet another, use-case for an apollo-server-types package!

I've opened #2970 to track the actual chore necessary to make that happen, but closing this bug is dependent on that getting resolved!
