[🚀esl-event-listener]: introduce a simple way to resubscribe listeners

[ala-n]

As an ESL user, I may want to resubscribe a group of subscription in the most efficient way.

At the current state of things:

// Resubscribe consist of direct unsubscribe
this.$$off(this._onEvent1);
this.$$off(this._onEvent2);
this.$$on(this._onEvent1);
this.$$on(this._onEvent2);

It is requested to provide the following API:

this.$$reset(this._onEvent1);
this.$$reset(this._onEvent2);

it is requested to have the following ways as well:

this.$$reset('click');

// https://github.com/exadel-inc/esl/issues/2381
this.$$reset({group: 'group'});

// That one is definitely nice to have (we don't have this out of the box technically)
this.$$reset([this._onEvent1, this._onEvent2]);

Open questions:

• The name for Element API (Mixin and BaseElement): this.$$reset
• The name for low-level API: ESLEventUtils.resubscribe(...)

Open technical questions:

• Can we make this resubscriptions efficiently (only if required)?

--- Discussion Notes ----

• Positive vote:

this.$$reset(this._onEvent1);

this.$$reset('click');

// https://github.com/exadel-inc/esl/issues/2381
this.$$reset({group: 'group'});

• Rather negative vote (for now):

this.$$on({group: '..'});
this.$$on('click');

• Only if technically simple

this.$$reset([this._onEvent1, this._onEvent2]);

• Alt Naming
  • this.$$reinit + ( 3 2 3 2 1 1.5 3 )
  • this.$$reset ( 0 1 0 1 2 1.5 0 )
