change json field placeholder from 'asdf' to 'bar' (fix #1260)

[Anupam-dagar]

This changes the 'asdf' present in json field placeholder to 'bar'.

I have currently changed the placeholder text directly for edit and insert. Since the placeholders used are same, I suggest adding the placeholders to constant.js and importing them in both edit and insert js files.

Waiting for a review for the constants.js approach.

Update Commit

This PR changes the placeholder for JSON datatype. Along with it, the placeholders are now returned by the function defined in constants.js. This function was assigning the placeholder in InsertItem.js, now the function is in constants.js and imported in EditItem.js and InsertItem.js hence controlling the placeholders for both insert and edit components from one place.
Also, big integer and uuid datatype placeholders were missing from EditItem.js which are now added.

Fixes: #1260

@Anupam-dagar - As you pointed out, its better to put in the re-used placeholders in a constants file. Look out for such existing files and see if you could add these to them instead of creating a new one.

[Anupam-dagar]

@praveenweb sure, I will do that.
