Import only lodash submodules

[yurishkuro]

In order to reduce the bundle size, lodash recommends importing submodules, e.g. import _get from 'lodash/get' instead of import { debounce } from 'lodash'. Most of our code is already like that, with the exception of just a handful of files:

$ grx lodash packages/*/src | grep -v 'lodash/'
packages/jaeger-ui/src/components/DependencyGraph/DependencyForceGraph.jsx:18:import { debounce } from 'lodash';
packages/jaeger-ui/src/components/TracePage/TraceStatistics/tableValues.tsx:16:import * as _ from 'lodash';
packages/jaeger-ui/src/components/TracePage/TraceStatistics/generateDropdownValue.tsx:15:import _ from 'lodash';
packages/jaeger-ui/src/components/SearchTracePage/SearchResults/ResultItem.tsx:20:import { sortBy } from 'lodash';

This ticket is to clean up these remaining full imports by replacing them with the needed submodule imports.

It will be interesting to see how much it would affect the bundle size:

Hey, @yurishkuro! I would like to work on this.

Can you please tell how did you generated this bundle size visualization.
