[Beats CM] Re-arch table assignment control definitions

[justinkambic]

Changes

The goal of these changes is to simplify the definition of assignment options for tables, and to make the components that handle the options and their associated actions more generic.

The layout and associated properties of the assignment options can now be defined like this:

export const beatsListAssignmentOptions: AssignmentControlSchema[] = [
  {
    type: AssignmentComponentType.Action,
    grow: false,
    name: 'Disenroll selected',
    showWarning: true,
    warningHeading: 'Disenroll beats',
    warningMessage: 'This will disenroll the selected beat(s) from centralized management',
    action: AssignmentActionType.Delete,
    danger: true,
  },
  {
    type: AssignmentComponentType.Popover,
    name: 'Set tags',
    grow: false,
    lazyLoad: true,
    children: [
      {
        name: 'Assign tags',
        type: AssignmentComponentType.TagBadgeList,
      },
    ],
  },
  {
    type: AssignmentComponentType.SelectionCount,
    grow: true,
    name: 'selectionCount',
  },
];

Any objects and an action handler are specified at the declaration of the table component:

<Table
  assignmentOptions={{
    items: this.state.tags || [],
    schema: beatsListAssignmentOptions,
    type: 'assignment',
    actionHandler: this.handleBeatsActions
  }}
  items={sortBy(this.state.beats, 'id') || []}
  ref={this.state.tableRef}
  type={BeatsTableType}
/>

There're three ways to display assignment options:

• none:
  There are no controls displayed for the table.
  

• primary:
  When items are selected, the option is displayed next to the normal controls. This is appropriate when the controls perform actions only on the selected objects.
  

• assignment:
  When items are selected, the actions replace the normal controls. This is appropriate when there will be association between the table's selected objects and some other list of objects or resources.

@mattapperson I've updated this PR with significant additions after merging in the latest changes to the feature branch - so it may be worth an additional look before we merge.
