Generates a property filter condition string. Creates a formatted string to use in a filter expression that uses
the specified operation to compare the property with the value, formatted as the specified {@link EdmType}.

@param propertyName
A <code>String</code> which specifies the name of the property to compare.
@param operation
A <code>String</code> which specifies the comparison operator to use.
@param value
A <code>String</code> which specifies the value to compare with the property.
@param edmType
The {@link EdmType} to format the value as.
@return
A <code>String</code> which represents the formatted filter condition.
