[BUG] New Vault module doesn't respect verify option (3007.0)

[voyvodov]

Description
The new vault module has a bug in unwrap function.
While other calls are respecting if verify option is set to False or CA file by utilizing self.request, unwrap is doing call on it's own, which results in missing verify option.
However, since in the init, there is check if verify is set to exact certificate and verify is set on requests Session this will work.

Setup
(Please provide relevant configs and/or SLS files (be sure to remove sensitive info. There is no general set-up of Salt.)

Please be as specific as possible and give set-up details.

• on-prem machine
• VM (Virtualbox, KVM, etc. please specify)
• VM running on a cloud service, please be explicit and add details
• container (Kubernetes, Docker, containerd, etc. please specify)
• or a combination, please be explicit --> Any kind of machines
• jails if it is FreeBSD
• classic packaging
• onedir packaging
• used bootstrap to install

Steps to Reproduce the behavior
Setup Vault server or cluster with self-signed certificate.
Point Salt master to that cluster and set server.verify option to CA file, e.g.

vault:
  server:
    urls: http://localhost:8200
    verify: /etc/salt/vault-ca.crt
...

Try to issue any of the vault actions via salt-call

Expected behavior
Salt master and minions should respect verify option as documented.
