Add support for auth via security_token

[bjoern-reetz]

In dev, I work with security_token auth method and everything works fine with the OCI CLI (the CLI also supports setting $OCI_CLI_AUTH=security_token). I would appreciate to have support for the same auth method in ocifs.

Hi Björn,
We will add tighter integration for this, thank you for reaching out!
In the meantime, you can still use this signer by doing the following:

import oci
import ocifs

config = oci.config.from_file(profile_name='TokenDemo')
token_file = config['security_token_file']
token = None
with open(token_file, 'r') as f:
     token = f.read()
private_key = oci.signer.load_private_key_from_file(config['key_file'])
signer = oci.auth.signers.SecurityTokenSigner(token, private_key) 
fs = ocifs.OCIFileSystem(signer=signer, region="us-ashburn-1")

(Security Token logic taken from here: https://docs.oracle.com/en-us/iaas/Content/API/SDKDocs/clitoken.htm )

Thanks for the quick reply! This is great news and I am looking forward to having native support so I can use oci://bucket@namespace/my-object in combination with security_token.

Hello, any progress on this already? I noticed there was a pull request filed to resolve this, as far as I can tell it was not merged yet.
