Make inlets-operator not fail on existing secret

[hasheddan]

In order for the inlets-operator app to not fail on re-runs
it is necessary for the command to be resilient to the
inlets-access-key secret already being present in cluster.

Description

Currently, running k3sup app install inlets-operator after it has already been run once will fail due to the presence of the inlets-access-key secret already being present. This change updates behavior to log when the secret is already present, but to continue execution using the existing secret.

Motivation and Context

• I have raised an issue to propose this change (required)

Fixes #172

How Has This Been Tested?

Running installation for the first time on a k3s cluster set up using k3sup:

. This could be changed in the future if it is desirable not to always show the kubectl output immediately.
