As a developer I want to create the network connections page

The network connections page should follow the design created in Figma: https://www.figma.com/file/SEwWpo68UI92SNSookfyTp/UI?node-id=2664%3A472459

This feature involves:

• creation of the table
• creation of the toolbar
• creation of the side panel
