> Attempting to parse complex types in PipelineOptions can have a suboptimal 
> UX.  For example, if the option type being parsed is an Instant, simply 
> passing in:
> {{--myInstant=2021-07-17 }}{{will fail.  Instead the user must pass in 
> --myInstant="2021-07-17"}}{{, however, this is complicated by the fact that 
> the quotes will be stripped from the arguments in many cases, requiring a 
> user to actually pass in --myInstant='"2021-07-17"'.  }}
> This can be improved by attempting to parse the input twice, once as-is, and 
> then trying again by automatically wrapping it in quotes.
> Additionally, it's impossible to use a custom JsonDeserializer on a pipeline 
> option property.  We should allow using @JsonDeserialize on the getters to 
> supply a custom one.
