Exposing _counter and having value as a param in add_periodic_callback

[ahuang11]

I was thinking that it'd be useful to have _counter as a public method/to show in periodic.params()?

import panel as pn
pn.extension()

test = pn.widgets.Toggle(name='Test')

def toggle():
    test.value = not test.value

periodic = test.add_periodic_callback(toggle, 1000)
print(periodic._counter)

Also maybe periodic.value = True mapped to periodic.start() and periodic.value = False mapped to periodic.stop() so there's less boilerplate and can use a .link() / .jslink() directly with a toggle

def toggle_periodic_callback(event):
    if event.new is True:
        periodic_cb.start()
    else:
        periodic_cb.stop()

becomes
toggle.jslink(periodic, value='value')

toggle.jslink(periodic, value='value')

Note this cannot work since the value toggle would be server-side, .link would work though.

This would be an API change and users could simply keep their own counter so I'm -1 and will close.

Also the other part of this proposal was implemented. You can now set the running parameter on PeriodicCallback.
