Update apollo-server-express in /modules/api from 1.3.4 to 2.2.5

[ghost]

Dependencies.io has updated apollo-server-express (a npm dependency in /modules/api) from "1.3.4" to "2.2.5".

2.2.5

• Follow-up on the update to graphql-playground-html in previous release by also bumping the minor version of the graphql-playground-react dependency to 1.7.10 — which is the version requested from the from the CDN bundle by graphql-playground-html. PR #2037

2.2.4

• Fix GraphQL Playground documentation scrolling bug in Safari by updating to latest (rebased) fork of graphql-playground-html. PR #2037

2.2.3

• When generateClientInfo is not used to define the client name, client version and
  client reference ID, Apollo Server will now default to the values present in the HTTP headers
  of the request (apollographql-client-name, apollographql-client-reference-id and
  apollographql-client-version respectively). As a last resort, when those headers are not set,
  the query extensions' clientInfo values will be used. PR #1960

2.2.2

• Fixed TypeScript 2.2 compatibility via updated apollo-tooling dependency. Issue #1951 26d6c739
• Throw a more specific error when asynchronous introspection query behavior is detected. PR #1955

2.2.1

• Added support for an array of modules on the ApolloServer constructor options. Each element of the modules can point to a module which exports typeDefs and resolvers. These modules can be used in lieu of, or in combination with, directly specifying schema or typeDefs/resolvers on the constructor options. This provides greater modularity and improved organization for logic which might be limited to a specific service. 8f6481e6.
• Added resolveObject support to query execution. bb67584.
• Fix broken apollo-server-cloud-functions in 2.2.0 caused by missing TypeScript project references which resulted in the package not being published to npm in compiled form. PR #1948

2.2.0

• New request pipeline, including support for plugins which can implement lifecycle hooks at various stages of a request. PR #1795.
• Introduce new apollo-server-testing utilities. PR #1909
• Fix mocks configuration to allow disabling of mocks by using mocks: false, even if mockEntireSchema is true. PR #1835
• Update graphql-playground-html to 1.7.8. PR #1855
• Bring back Azure functions support Issue #1752 PR #1753
• Allow an optional function to resolve the rootValue, passing the DocumentNode AST to determine the value. PR #1555
• Follow-up on the work in PR #1516 to also fix missing insertion cursor/caret when a custom GraphQL configuration is specified which doesn't specify its own cursorShape property. PR #1607
• Azure functions support Issue #1752 PR #1753 PR #1948
• Allow JSON parsing in RESTDataSource of Content Type application/hal+json. PR #185
• Add support for a requestAgent configuration parameter within the engine configuration. This can be utilized when a proxy is necessary to transmit tracing and metrics data to Apollo Engine. It accepts either an http.Agent or https.Agent and behaves the same as the agent parameter to Node.js' http.request. PR #1879
