fix: node kerberos cache volume name

Using the linux.krb5CacheDirectory helm option doesn't work due to an invalid volume name:

spec.volumes[0].name: Invalid value: "krb5Cache-dir": a lowercase RFC 1123 label must consist of lower case alphanumeric characters or '-',
and must start and end with an alphanumeric character (e.g. 'my-name',  or '123-abc', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?')
