Enable samlet to create aws cred secrets in the remote clusters

[ytsarev]

We can hugely benefit from enabling samlet ability to push secrets down to target remote clusters.

It will enable us to:

• Keep sensitive 'root' service credentials(the one with access rights to generate new token) withing a single cluster
• Solve saml auth blocker with infrastructure SaaS providers like Upbound Cloud

Doable, we can leverage https://github.com/admiraltyio/multicluster-controller , but can't tell ATM how huge the effort could be.

@k0da not sure, maybe simple remote API kick with Service resource creation will be a simpler solution. We don't need sophisticated machinery here I guess. Please correct me if I am wrong
