Add multi-message produce feature

[xpr3sso]

Hi @tchiotludo,

This feature allows the user to input multiple records as key-value pairs at once as one-liners like:

key1:{"value": 41}
key2:{"value": 42}

or

key1_{"value": 41};key2_{"value": 42}

This can help when dealing with larger sets of generated data - there is a limit for the request size, though :D
Multiple key-value separators can be chosen from, to support various naming conventions people might have.

Looks like this on the front end:

The "Key" field gets disabled when "Multiple messages" is selected, the multi-message fields for standard "Single message" producing. Placeholders for both modes are added to give some guidance.

What do you say? Could this be useful in general?

Hi :)
I think it's a cool features ! Thanks for this one :)
My first impression (without a lot of reflexion) :
Maybe we can use a standard method for this multiple message (in order to handle key ?
Maybe :

key1,{"id": "123"}
key2,{"id": "456"}

or

{"key": "key1","value": {"id": "123"}}
{"key": "key2","value": {"id": "456"}}

A simple checkbox for multiple message, and we display a notice about the format needed ?

What do you think about that ?

Good idea! The checkbox combined with a text field for the separator would do the job. Let me check and get back to you :)
The second example would save some trouble with splitting the values manually, but also adds some overhead - e.g. when you think of copying some lines from a spreadsheet to produce them.

Alright, was just able to try some layout variants. This is how the result looks like:

Looks way cleaner and key-value pairs can be split with any char(-combination) the user provides ;)

@xpr3sso : does this one can be review ?

[xpr3sso]

Hi @tchiotludo,
yes, should be ready for review now :) No quite sure why some tests are failing now, though.

thanks @xpr3sso works great 👍
