Remove limit on template params length

[margalva]

Remove limit on parameters input field. Work-around while a better implementation is designed.

@margalva @viseshrp You are not concerned about backward compatibility here? I was just thinking that the maximum length is server API specific, assuming the server protocol number changed with the maximum length change.

[margalva]

@randallfrank As we're opening up the limit so now it's larger than it used to, it shouldn't pose backward compatibility issues, as far as I see it. Old cases will work with the new API. New cases won't work against old APIs, but that's not the suggested direction anyway - we don't even let you start a server from an old version on top of a new database.

@randallfrank I fail to see the backwards incompatibility here as it is just an extension of the number of allowed chars, as @margalva has mentioned. I also don't see the need to bump the server version due to the restrictions stated above.
