[Feat]: Node Search

[ss-mbrancato]

Problem

There is no way in Netdata Cloud to search for a node other than using the ability to search in the browser.

Description

A box to allow a user to search for a node at least by the name displayed in the nodes tab.

Importance

nice to have

Value proposition

1. Simplify finding the correct node

Proposed implementation

Data is already there, just needs a box to allow the search.
