Make it possible to add custom API documentation based on the deployment location

[t2gran]

Summary

This PR introduce a new configuration parameter to load a deployment specific properies file.

router-config.json

{
  "server": {
    "apiDocumentationProfile" : "entur",
 ...

custom-documentation-entur.properties

TariffZone.description=A **zone** used to define ...

Syntax properties file

Use:

<TypeName>[.<FieldName>].(description|deprecated)[.append]

Examples

Replace the existing type description

Quay.description=The place for boarding/alighting a vehicle

Append to the existing type description

Quay.description.append=This is appended

Replace the existing field description

Quay.name.description=The name of a Quay is ...

Append to the existing field description

Quay.name.description.append=(Source NSR)

Insert deprecated reason. Due to a bug in the Java GraphQL lib, an existing deprecated reason cannot be updated, but it can be deprecated if not already marked. Deleting the reason from the schema, and adding it back using
the "default" TransmodelApiDocumentationProfile can be used as a workaround. The problem is reported to the Java GraphQL Prodject here: graphql-java/graphql-java#3786.

Quay.name.deprecated=This field is deprecated ...

There are a few things that I picked up on, mainly that properties files in Java are assumed to be ISO-8869-1.
