This upgrades TypeScript to version 2.9.2. My main motivation is the support for generic type arguments in JSX elements and tagged templates (e.g. for styled-components).

Problems arising from breaking changes in the new TypeScript version have been mitigated by:

  • setting the keyofStringsOnly option until impacted code has been
    future-proofed
  • Restricting some joi-related generics

See the release notes for details.

Some follow-up tasks should be:

  • Update EUI to support the new keyof behaviour
  • Update new platform TypeScript code to support new keyof behaviour
  • Remove keyofStringsOnly setting

issue: hmm, I don't really like the signature of SchemaLike: string | number | boolean | object | null | Schema | SchemaMap since it exposes internal Schema and SchemaMap to the outside.

At this stage I'd rather prefer if we have something like export type ConditionalTypeValue = string | number | boolean | object | null; inside of conditional_type.ts that is re-exported in src/core/server/config/schema/types/index.ts and used here.

What do you think @weltenwort ?

LGTM once CI is green. Briefly tested locally, haven't noticed any issues. Thanks!

This resolves problems arising from breaking changes in the new
TypeScript version by...

* setting the `keyofStringsOnly` option until impacted code has been
  future-proofed
* Restricting some joi-related generics
