Add support for a tag suffix in values

[4ch3los]

TLDR: This pr adds a additional values field, to provide a suffix for the tag, like -ga, -ea, ... This helps when replicating the images from the s1 registry.

When directly replicating the images from containers.sentinelone.net, images get suffixed with their release state (ga/ea). This resulst in the need to adjust the tag values for each upgrade. With this pr you can just provide -ga/-ea as suffix for you tag and simply update the helm chart,

Can we use the current tag param?

Yes could definetly use the current tag param, but the downside is, that you always need to maintain your s1 version in two different locations(helm chart version + helm values).
With the option of a suffix, chart version and image version are in sync again. And you just need to update the chart when upgrading s1

@4ch3los Thanks for your PR.
Can you provide more information on why not using the tag param?

No longer needed, as values now contain the -ea or -ga by default, fine for me
