Dates.parse(::AbstractString, ::DateFormat) removed without deprecation

[omus]

Julia 0.5 had a Dates.parse function which could parse a string into an Array{Period}. The function was useful for parsing DateTimes which needed modification before constructing a DateTime object.

For example on Julia 0.5:

julia> df = Dates.DateFormat("yyyy-mm-dd HH:MM");

julia> DateTime("2016-03-03 24:00", df)
ERROR: ArgumentError: Hour: 24 out of range (0:23)
 in DateTime(::Int64, ::Int64, ::Int64, ::Int64, ::Int64, ::Int64, ::Int64) at ./dates/types.jl:149
 in DateTime(::Base.Dates.Year, ::Base.Dates.Month, ::Base.Dates.Day, ::Base.Dates.Hour, ::Base.Dates.Minute) at ./dates/types.jl:172
 in DateTime(::String, ::Base.Dates.DateFormat) at ./dates/io.jl:268

julia> Dates.parse("2016-03-03 24:00", df)
5-element Array{Base.Dates.Period,1}:
 2016 years
 3 months  
 3 days    
 24 hours  
 0 minutes 

In Julia 0.6

julia> Dates.parse("2016-03-03 24:00", Dates.DateFormat("yyyy-mm-dd HH:MM"))
ERROR: MethodError: no method matching parse(::String, ::DateFormat{Symbol("yyyy-mm-dd HH:MM"),Tuple{Base.Dates.DatePart{'y'},Base.Dates.Delim{Char,1},Base.Dates.DatePart{'m'},Base.Dates.Delim{Char,1},Base.Dates.DatePart{'d'},Base.Dates.Delim{Char,1},Base.Dates.DatePart{'H'},Base.Dates.Delim{Char,1},Base.Dates.DatePart{'M'}}})
Closest candidates are:

  parse(::AbstractString; raise) at parse.jl:230

Removed by #19545

@shashi, can we add that feature back within the new fast parsing framework? Otherwise it should technically be deprecated, but it seems like making it work would be even better as it's useful.

@StefanKarpinski I'm attempting to get a version of this working with 0.6
