Implement the --info option that takes a flag as an argument
and returns information about the TPM implementation. Only the

If the key is not readable as the current user, such as tss:tss,

Since the EK cert must have an Authority Key Id, we error out if
the signing certificate we are given does not have an Authority
Key Id. The typical reason why it wouldn't have it is that we are
using a self-signed (rootCA) certificate directly.

Update the test case test_swtpm_cert to have its issuercert signed

Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com>
We are currently missing the Authority Key Id in the certificate used for
creating the EK cert. To get this, we create a root CA for our local CA
and use that root CA to sign the local CA's certificate. Our local
CA is now an intermediate CA and the Authority Key Id can now be copied
into the EK cert.

Create the TPMSpecification SEQUENCE and add it to the subject

Address the issue that the pidfile needs to be removed at the end if
