Read configuration options from annotations

[stuebingerb]

KGraphQL should respect existing annotations for configuration options like property names (cf. #166), deprecations or ignored properties.

This should be completely optional and ideally not introduce new dependencies for consumers that do not need this functionality (e.g. by having it as a separate module).

Currently planned (open for discussion):

• @kotlin.Deprecated(<reason>) marks a property as deprecated with reason <reason>
• @kotlin.jvm.Transient sets the ignored of a property to true
• @kotlinx.serialization.Transient sets the ignored of a property to true
• @com.fasterxml.jackson.annotation.JsonIgnore sets the ignored of a property to true
• @kotlinx.serialization. SerialName(<value>) sets the name of a property to <value>
• @com.fasterxml.jackson.annotation.JsonProperty(<value>) sets the name of a property to <value>
