useless warning pollutes every CLI invocation `Warnf OS does not support credentials cache`

[dch]

Describe the bug

new credentials cache warning interferes with CLI usage.

To Reproduce

Query a vault server for a key/value lookup on FreeBSD, see unwanted warning on every invocation:

 vault read secret/test
WARN[0000]log.go:204 gosnowflake.(*defaultLogger).Warnf OS freebsd does not support credentials cache
Key                 Value
---                 -----
refresh_interval    72h
...

Expected behavior

This warning should never be shown to the user.

Environment:

$ vault status
WARN[0000]log.go:204 gosnowflake.(*defaultLogger).Warnf OS freebsd does not support credentials cache
Key             Value

Additional context

warning is new in last release.

[dereckson]

This message is emitted by gosnowflake library, so probably something worthwhile to fix upstream: the library prints a debug message on Linux if there is a failure while a warning if not supported.

That kind of fixes have already occured in the past, e.g. https://github.com/snowflakedb/gosnowflake/issues/1182

Upstream references:

• bug report: https://github.com/snowflakedb/gosnowflake/issues/1572 / SNOW-2331330
• code review: https://github.com/snowflakedb/gosnowflake/pull/1573/files

[dereckson]

Code has been merged upstream.

Next step: gosnowflake release

[dereckson]

released with gosnowflake v1.17.1

New gosnowflake library has been released with my fix to decrease the verbosity of the error message from warning to debug.

If you bump Vault to use 1.17.1+, this issue will be solved.
