Possible cipher suites values and tls versions in help for apiserver and kubelet

**What this PR does / why we need it**:
Addresses a suggestion made by @lavalamp to list the possible TLS cipher suites in the kubelet and apiserver helps: https://github.com/kubernetes/kubernetes/pull/48859#discussion_r162413223

**Which issue(s) this PR fixes** 
NONE

**Special notes for your reviewer**:
This pull request only adds to the help message the possible values of the TLS Cipher suites for Kubelet and api server.
It is an addition to the already merged PR https://github.com/kubernetes/kubernetes/pull/48859

The help output looks like this:

```
      --tls-cert-file string                                    File containing the default x509 Certificate for HTTPS. (CA cert, if any, concatenated after server cert). If HTTPS serving is enabled, and --tls-cert-file and --tls-private-key-file are not provided, a self-signed certificate and key are generated for the public address and saved to the directory specified by --cert-dir.
      --tls-cipher-suites strings                               Comma-separated list of cipher suites for the server. Values are from tls package constants (https://golang.org/pkg/crypto/tls/#pkg-constants). If omitted, the default Go cipher suites will be use.  Possible values: TLS_ECDHE_ECDSA_WITH_RC4_128_SHA,TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_RC4_128_SHA,TLS_RSA_WITH_AES_256_CBC_SHA,TLS_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256,TLS_RSA_WITH_3DES_EDE_CBC_SHA,TLS_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305,TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305,TLS_RSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_RSA_WITH_RC4_128_SHA,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384,TLS_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA
      --tls-min-version string                                  Minimum TLS version supported. Value must match version names from https://golang.org/pkg/crypto/tls/#pkg-constants.
      --tls-private-key-file string                             File containing the default x509 private key matching --tls-cert-file.

Use default seccomp profile for flutend-elasticsearch addons

**What this PR does / why we need it**:
This PR sets the default seccomp profile to 'docker/default' for:
- fluentd-es daemon set.
- kibana-logging deployment.

The elasticsearch-logging stateful set is still unconfined because it uses gce:podsecuritypolicy:privileged.

This PR is a followup of #62662. We are using 'docker/default' instead of 'runtime/default' in addons in order to handle node version skew. When seccomp profile is applied automatically by default later, we can remove those annotations.

This is PR is part of #39845.

Ensure that only IPs are used as node addresses in OpenStack LBs

**What this PR does / why we need it**:
ATM, when no InternalIP can be found for a node, the openstack cloud provider tries to create a LB with whatever is the first address it can find for the node. This could also be the hostname or a dns name.
However, LBaaS will reject anything that is not an IP address for pool members. Therefore a meaningful error should be returned instead of just returning the first address of the node, even if it is clear that this will lead to an error in LBaaS.

Fixes #64317

kubeadm: Add a 'kubeadm config migrate' command

**What this PR does / why we need it**:

This is an UX improvement so users may easier "upgrade" their **configuration files** from the an old version (e.g. `v1alpha1`) version to a new one (e.g. `v1alpha2`), can do this **locally and seamlessly without touching a cluster**. We talked about this in the SIG meeting; getting the users to be able to convert their checked-in configuration files to new API versions will be crucial.

**Special notes for your reviewer**:

**Release note**:

```release-note
kubeadm: Add a 'kubeadm config migrate' command to convert old API types to their newer counterparts in the new, supported API types. This is just a client-side tool, it just executes locally without requiring a cluster to be running. You can think about this as an Unix pipe that upgrades config files.

fix parsing 'crictl pods -q' output

**What this PR does / why we need it**:

fix parsing 'crictl pods -q' output
Output of crictl pods -q is a list of running pod ids, one id per line.
Current code splits this output incorrectly which makes next command
'crictl stopp' fail if there is more than one pod running.

Should be fixed by using strings.Fields instead of strings.Split.
