Add structure logging (Zap) to Vitess

[EmadMokhtar]

Description

The goal of this PR is to introduce the structure logging to Vitess. Vitess is using glog as logger. So I decided to use noglog and create drop-in replacement. I used Zap log to replace glog.

The PR is also introducing a flag structure_logging where the user can choose to use structure logging or the default logging. The default value is False so the default is to use the current logging glog.

• If this is a change that users need to know about, please apply the release notes (needs details) label so that merging is blocked unless the summary release notes document is included.
• If a test is added or modified, there should be a documentation on top of the test to explain what the expected behavior is what the test does.

If a new flag is being introduced:

• Is it really necessary to add this flag?
• Flag names should be clear and intuitive (as far as possible)
• Help text should be descriptive.
• Flag names should use dashes (-) as word separators rather than underscores (_).

If a workflow is added or modified:

• Each item in Jobs should be named in order to mark it as required.
• If the workflow should be required, the maintainer team should be notified.

Bug fixes

• There should be at least one unit or end-to-end test.
• The Pull Request description should include a link to an issue that describes the bug.

Non-trivial changes

• There should be some code comments as to why things are implemented the way they are.

New/Existing features

• Should be documented, either by modifying the existing documentation or creating new documentation.
• New features should have a link to a feature request issue or an RFC that documents the use cases, corner cases and test cases.

Backward compatibility

• Protobuf changes should be wire-compatible.
• Changes to _vt tables and RPCs need to be backward compatible.
• vtctl command output order should be stable and awk-able.
• RPC changes should be compatible with vitess-operator
• If a flag is removed, then it should also be removed from VTop, if used there.

This is a second trial for this. The pervious PR #11960 is reverted. Here is the revert PR #12219 and there you'll find more context.

I don't see the need to prefix the new files with vts_, they can just be logger.go and logger_test.go.
We don't do that anywhere else.

There are files with the same name. I intend to keep the structure logging separated in a different file.
