[new] Many features related to index and filtering

[mokaddem]

• Improved existing features in bootstrap helpers (components & JS) and added more components (alert, table, badge, modal)
• Improved CLI tools (importer & fieldSquasher)
• Various fixes in CRUDComponent
• Index's contextual filters improved to support multi-conditions, negations, LIKE and multi-hop associations:

  [
  [
      'field' => 'constituency',
      'value LIKE' => '%Government%',
  ],
  [
      'field' => 'csirt-network-status',
      'value !=' => 'Member',
  ],
  ]

• Index's contextual filters improved to support custom query builder

  [
  'label' => __('CIRCL only'),
  'filterConditionFunction' => function($query) {
      return $query->where(['name' => 'CIRCL']);
  }
  ]

• Advanced filtering for index based on allowed filters
