Bug #17766: Net::HTTP verify_callback is called three times when opening a connection
https://bugs.ruby-lang.org/issues/17766

* Author: jecain (Jim Cain)
* Status: Open
* Priority: Normal
* ruby -v: 2.7.2
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN
----------------------------------------
I've noticed that verify_callback is called three times when opening a connection. Here is an example: (Change "localhost" to whatever host can receive an HTTPS connection.)

```
ruby -e 'require "net/http"; Net::HTTP.start("localhost", 443, nil, nil, nil, nil, use_ssl: true, verify_callback: ->(v,s){puts "verify_callback"; true}) {}'
```

The output:

```
verify_callback
verify_callback
verify_callback
```

This requires awkwardness in the callback to account for the multiple calls per single connection.
