[Logs UI] Replace Query Bar with EuiSuggest component and fix performance issues

[Zacqary]

Kibana version:
7.6

Browser version:
Firefox 71 and Chrome 79

Browser OS version:
MacOS 10.14.6

Describe the bug:
Typing a character into the Query Bar on the Logs Stream page sometimes takes a second or more to display the character typed. This is due to performance issues with the autocomplete box.

@simianhacker suggested using the Saved Search with Filter component to alleviate this issue

As per discussion below, we should fix performance issues in the kuery parser, and use the EuiSuggest component, to alleviate these issues.

Given that using the "Saved Search with Filter" adds a lot more complexity and new features I feel these should be treated separately:

1. Fix potential performance problems in the kuery parser and replace the filter bar with an EuiSuggest component.
2. Deliberate introducing the "Saved Search with Filter" component and clarify possible roadblocks (e.g. Kibana index pattern dependencies).

We should wait on this until we've investigated the SearchBar component from the data plugin to see if it's an easy drop-in replacement that solves most of these issues. See #53123 (comment)

and #53310
