Chart spacing in monitor dashboard needs to be fixed

Summary

• Group titles and chart titles should be left-aligned
• Spacing on the right and left edges of the chart rows should be equal
• Spacing between the rows needs to be increased (should be at least 24px)
• Alignment is also off in some places.

Steps to reproduce

1. Pre-req: A project with prometheus installed.
2. Navigate to Operations > Metrics
3. Notice the spacing between the charts and also the padding between left/right borders (check screenshot)
