allow users to check if specific cpu flags are supported by the host.
```yaml
apiVersion: troubleshoot.sh/v1beta2
kind: HostPreflight
metadata:
name: ec-cluster-preflight
spec:
collectors:
- cpu: {}
analyzers:
- cpu:
checkName: CPU
outcomes:
- pass:
when: hasFlags cmov,cx8,fpu,fxsr,mmx
message: CPU supports all required flags
- fail:
message: CPU not supported
```
allows troubleshoot to collect and analyze CPU micro architecture. this
is an usage example:
```yaml
apiVersion: troubleshoot.sh/v1beta2
kind: HostPreflight
metadata:
name: ec-cluster-preflight
spec:
collectors:
- cpu: {}
analyzers:
- cpu:
checkName: CPU
outcomes:
- pass:
when: 'supports x86-64-v2'
message: CPU supports x86-64-v2
- fail:
message: CPU does not support x86-64-v2
```
* feat: Add regular expressions host anaylser
This anaylser is the same as the in-cluster text anaylser. You pass in
search expressions to find values in files collected in a bundle
* additional test assertion to check analyser warn
Fixed bug caused by host preflights not handling empty when clauses, this cropped up because we now handle multiple host preflight results. Also expanded test coverage and added integration test script.
