+${CMD} - simple tool for fixing onap helm deployment
+
+DESCRIPTION
+ This script does nothing smart or special it just tries to
+ redeploy onap component. It can fix only problems related to
+ race conditions or timeouts. Nothing else. It will not fix
+ broken ONAP - there is no such ambition - that effort should
+ be directed in the upstream.
+
+USAGE
+ ${CMD} -h|--help
+ This help
+
+ ${CMD} -n|--namespace <namespace>
+ (-f|--file <override>)...
+ (-s|--storage <directory>)|--no-storage-deletion
+ [-p|--release-prefix <release prefix>]
+ [-t|--timeout <secs>]
+ [(-c|--component <component release name>)...|
+ (-D|--delete-all)]
+ [-C|--clean-only]
+
+ Usage 1 (simple heuristics - redeploy failed components):
+ ${CMD} -n onap -f /some/override1.yml -s /dockerdata-nfs
+
+ Usage 2 (redeploy ONLY explicit listed components):
+ ${CMD} -n onap -f /some/override1.yml -s /dockerdata-nfs \
+ -c onap-aaf -c onap-sdc -c onap-portal
+
+ Usage 3 (delete EVERYTHING and redeploy):
+ ${CMD} -n onap -f /some/override1.yml -s /dockerdata-nfs \
+ --delete-all
+
+ Usage 4 (just clean - do not redeploy)
+ ${CMD} -n onap -f /some/override1.yml -s /dockerdata-nfs \
+ --delete-all --clean-only
+
+ Namespace argument and at least one override file are mandatory
+ for this script to execute. Also you must provide path to the
+ storage or explicitly request to not delete file storage of the
+ component.
+
+ Storage should be directory where persistent volume resides. It
+ will work only if component created a persistent volume with the
+ same filename as its release name. Otherwise no effect. The
+ exception is when '--delete-all' is used - in that case all
+ content of the storage is deleted (because ONAP is not consistent
+ with the volume directory names - eg.: sdnc).
+
+ CAUTION 1: filename of an override file cannot contain whitespace!
+ This is actually helm/onap deploy plugin issue which does not
+ handle such files. So I dropped the more complicated version of
+ this script when there is no reason to support something on what
+ will helm deploy choke anyway.
+
+ '--prefix' option is helm release argument - it is actually prefix
+ when you list the helm releases - helm is little confusing here.
+
+ CAUTION 2: By default release prefix is 'onap' - if you deployed
+ release 'onap' and now run this script with different prefix then
+ it will skip all 'onap-*' components and will deploy a new release
+ with new prefix - BEWARE TO USE PROPER RELEASE PREFIX!
+
+ Timeout set the waiting time for helm deploy per component.
+
+ '--component' references to release name of the chart which you
+ want to redeploy excplicitly - otherwise 'ALL FAILED' components
+ will be redeployed. You can target more than one component at once
+ - just use the argument multiple times.
+
+ Component option is mutually exclusive with the '--delete-all'
+ which will delete all components - healthy or not. Actually it will
+ delete the whole NAMESPACE and everything in it.
+
+ '--clean-only' can be used with any usage: heuristics, explicit
+ component list or with '--delete-all'. It basically just skips the
+ last step - the actual redeploy.
