[Feature Request] Persistent tooltips

Problem to solve

This is useful for placing clickable elements (e.g. a link) inside tooltip. Currently we can only increase closeDelay but it would be better to add a prop that would make a tooltip persistent - it wont close when hovered

Proposed solution

Currently I use a custom wrapper for this, I think this can be included as part of core package

<template>
  <v-tooltip v-bind="$attrs" ref="tooltip">
    <slot name="activator" slot="activator"/>
    <div @mouseenter="persistTooltip" @mouseleave="closeTooltip">
      <slot/>
    </div>
  </v-tooltip>
</template>

<script>
  export default {
    name: 'PersistentTooltip',
    inheritAttrs: false,
    methods: {
      persistTooltip() {
        this.$refs.tooltip.runDelay('open')
      },
      closeTooltip() {
        this.$refs.tooltip.runDelay('close')
      },
    },
  }
</script>

This can be achieved by assigning both disabled and v-model to the same prop https://codepen.io/anon/pen/ZwvymM
