[Gauge] Use EC library instead of the vislib one

[Kuznietsov]

Introduction

In order to the issue, it is required to add support of some features, absent at the gauge visualization from expression_charts, but used at vislib's gauge. Some of these features are blocked on the side of elastic-charts and will be addressed separately. The others will be encountered at this issue and addressed at the follow-up PRs.

Required features:

• Add support of arc/circle shapes.
• Add support of the show/hide scale functionality. (Add hide option to the ticksPosition argument)
• Add support of visdimensions at *Accessor args.
• For the purpose of the consistency, change metricAccessor, minAccessor, maxAccessor, goalAccessor to metric, max, min, goal. Don't have a strong opinion about it, but it seems to me very logical. @stratoula, @flash1293, WDYT?

Updates:

• Add transparent background
• Add percentage mode for support of legacy behavior
• Move current implementation of band colors to getColorForValue from custom palette (it supports continuity).
• Add logDatatable functionality to the gauge expression function.
• Support of overriding colors.

After delivering required features by elastic-charts

• [Goal] Full circle is cut off when container is resized elastic-charts#1598
• [Goal] Resizing limitations. elastic-charts#1599
• [Goal] Labels and values. elastic-charts#1600
• [Goal] Small-multiples details elastic-charts#1601
• [Goal] Outline for the goals of the white color. elastic-charts#1602

should be added:

• Outlines
• Small multiples
• Alignment
