Work around issues with urllib and LIST request method

[ethanhs]

When using hvac I ran into an issue where I kept getting 400: Bad Request when I tried to list secrets.

The following gives me a 400:

from urllib.request import Request, urlopen
urlopen(Request(url='https://server/v1/mount/metadata/folder', headers={'X-Vault-Token': 'my-token'}, method='LIST'))

However using the list=true query parameter and GET:

from urllib.request import Request, urlopen
urlopen(Request(url='https://server/v1/mount/metadata/folder?list=true', headers={'X-Vault-Token': 'my-token'}, method='GET'))

The request works fine.

I've been able to reproduce this issue across Linux/Python 3.7 and Windows/Python 3.9

Could hvac switch to using the query parameter to work around this issue?

If you initialize hvac.Client with strict_http=True, it will rewrite the LIST requests as GETs with the list query parameter: #689

Hi guys!

I faced with similar issue with the PKI secrets engine:

hvac.exceptions.InvalidRequest: Bad Request, on list https://vault_domain/v1/pki/issuers

According to the the advice but when I'm changing this parameter strict_http to "True" in adapters I'm facing a new issue for PKI secrets engine:

hvac.exceptions.InvalidPath: 1 error occurred:
* unsupported path

, on get https://vault_domain/v1/pki/issuer

Seems that after changing to the GET request it's using the wrong API URL (GET request used for read_issuer method). I'm facing this issue in all list methods (e.g. list_certificates, list_roles etc.)

I have Python 3.11 version, hvac version 2.3.0
