Remove UNSAFE lifecyle methods from React components

[tiffon]

Requirement - what kind of business use case are you trying to solve?

Remain compatible with React upgrades.

Problem - what in Jaeger blocks you from solving the requirement?

Some code needs to be changed. See the UNSAFE_* methods in The Component Lifecycle.

Proposal - what do you suggest to solve the problem or improve the existing situation?

Do not use the unsafe methods.

By my check, branch master no longer has any component methods of componentWillMount, componentWillUpdate, or componentWillReceiveProps or with an UNSAFE_ prefix.

I think this issue is safe to close.
