Jay Faulkner 79715dd750 Add element to configure IPA with TLS, use configdir 
First, this change preconfigures IPA to use a configdir. This will
permit deployers to add or modify IPA configuration in elements.
This change was a prerequisite to adding additional DIB elements
which require configuration.

Additionally, this adds a DIB element to configure TLS support for
IPA's API. If added to a ramdisk build with no configuration, it
will create a self-signed certificate and configure IPA to use it.
It also exposes various environment variables to allow deployers
to use preexisting certificates or CA files.

ironic-python-agent-tls

Adds TLS support to ironic-python-agent-ramdisk.

If enabled without any environment variables set to modify configuration, this element will enable TLS API support in IPA with a self-signed certificate and key created at build time.

Optionally, you can provide your own SSL certifiate and key, and optionally ca, via the following environment variables. They should be set to an accessible path on the build systems filesystem. If set, they will be copied into the built ramdisk, and IPA will be configured to use them.

The environment variables are:
  • DIB_IPA_CERT_FILE should point to the TLS certificate for ramdisk use.
  • DIB_IPA_KEY_FILE should point to the private key matching DIB_IPA_CERT_FILE.
If having a certificate generated, you can configure how it's generated:
  • DIB_IPA_CERT_HOSTNAME the CN for the generated certificate. Defaults to "ipa-ramdisk.example.com".
  • DIB_IPA_CERT_EXPIRATION expiration, in days, for the certificate.

    Defaults to 1095 (three years).

Note that the certificates generated by this element are self-signed, and any nodes using them will need to set agent_verify_ca=False in driver_info.

This element can also configure client certificate validation in IPA. If you wish to validate client certificates, set DIB_IPA_CA_FILE to a CA file you wish IPA client connections to be validated against. This CA file will be copied into the built ramdisk, and IPA will be configured to use it.
