> The function schema_of_json doesn't accept any options currently but the options can impact on schema inferring. Need to support the same options that from_json() can use on schema inferring. Here is examples of options that could impact on schema inferring:
> * primitivesAsString
> * prefersDecimal
> * allowComments
> * allowUnquotedFieldNames
> * allowSingleQuotes
> * allowNumericLeadingZeros
> * allowNonNumericNumbers
> * allowBackslashEscapingAnyCharacter
> * allowUnquotedControlChars
> Below is possible signature:
> {code:scala}
> def schema_of_json(e: Column, options: java.util.Map[String, String]): Column
> {code}
