Renew certificates of the nodes.

If the certificates from a node need to be renewed, the only way to do that now is by removing and re-adding the node with the new certificates.

This can be done:

1. With the UI.

2. With the command line.

3. With the PMM API.

Reference for the command line command:

Reference for the PMM API:

• Unregister node - link

• Add MongoDB service - link

It would be nice if PMM could renew the certificates with some command or button in UI to refresh the certificates and reload them from the files used when the node was added to PMM.

Or an option to update them in the UI or by using the command line with a command something like this:

So basically this is a request to have a different method to update the certificates other than un-registering and re-registering the services.
