[TDI-1361] make the avro serialization exception message more verbose

[apanourgiasfc]

Avro error messages now include the relevant path and topic.

On type errors:

• the path points to the attribute that caused the error
• we'll also include the data of said attribute

On any other error (e.g missing/unknown):

• the path points to the map the attribute that caused the error belongs

Error message examples

Incorrect Union type - :my-attribute is an enum and we supply a string:

{:message "java.lang.String is not a valid type for union [NULL, ENUM]", :path [:my-attribute], :data "Something", :topic "topic-name-1"}

Incorrect type for nested field :name of map :person:

{:message "java.lang.Long is not a valid type for string", :topic "topic-name-1", :path [:person :name], :data 123}

Unknown field :application-id2 in top level:

{:message "Field application_id2 not known in topic_name", :topic "topic-name-1", :path []}

Unknown nested field :name2 in :person map:

{:message "Field name2 not known in topic_name", :topic "topic-name-1", :path [:person], :data {:name "John", :name2 "dasds", :surname "Doe"}, :path [:person]}
