MsalClientException exception thrown when token not found in cache

[y0geshdev]

Describe the bug
When a token is not found in the in-memory cache then Azure identity log it as an MSAL exception.
The log level is a bit misleading if there is a cache miss. A warning level log might be better suited than an error log.

Or is it that I am missing something to configure it properly to avoid ERROR level log on cache miss?

To Reproduce
Steps to reproduce the behavior:

• Added code snippet to reproduce

Code Snippet
Add the code snippet that causes the issue.

                // create a clientCertificateCredential
                ClientCertificateCredential clientCertificateCredential = new ClientCertificateCredentialBuilder()
                        .tenantId(<Tenant_Id>)
                        .clientId(<Client_Id>)
                        .pemCertificate(<Certificate_Path>)
                        .sendCertificateChain(true)
                        .additionallyAllowedTenants("*")
                        .build();

                // create SecretClient using above credentials
                SecretClient client = new SecretClientBuilder()
                        .vaultUrl(<Vault_Url>)
                        .credential(clientCertificateCredential)
                        .buildClient();

                // get KV secret
                KeyVaultSecret spClientIdKvSecret;
                try {
                    spClientIdKvSecret = client.getSecret(<SECRET_NAME>);
                } catch (Exception ex) {
                    log.error("Unable to fetch service principal client ID secret from customer {} KV. Exception: {}",
                            destConfig.getAkvUrl(), getStackTrace(httpEx));
                    throw new ConfigurationException(format("Unable to fetch service principal client ID secret from customer %s KV.", destConfig.getAkvUrl()), httpEx);
                }

Expected behavior
Logging cache miss at a warning level might be better than logging it at error level.
