Duplicate ci_pagination_api_mixin.js into pipelines_pagination_api_mixin.js and environments_pagination_api_mixin.js

Problem

The ci_pagination_mixin.js is being used in to different areas of the product, Environments and Pipelines, and both are maintained by different teams ~"group::release" and ~"group::continuous integration".

Changes to ci_pagination_mixin.js may bring unexpected consequences.

Proposal

Duplicate the logic ci_pagination_mixin.js and go our separate ways, so each team can refactor as needed.

Now:

~/vue_shared/mixins/ci_pagination_api_mixin.js is used by:

• ~/commit/pipelines/pipelines_table.vue
• ~/environments/components/environments_app.vue
• ~/environments/folder/environments_folder_view.vue
• ~/pipelines/components/pipelines_list/pipelines.vue

Proposed:

~/environments/mixins/environments_pagination_api_mixin.js (same as ci_pagination_api_mixin) is used by:

• ~/environments/components/environments_app.vue
• ~/environments/folder/environments_folder_view.vue

~/pipelines/mixins/pipelines_pagination_api_mixin.js (same as ci_pagination_api_mixin) is used by:

• ~/commit/pipelines/pipelines_table.vue
• ~/pipelines/components/pipelines_list/pipelines.vue
