Auto merge of #2040 - Turbo87:template-lint, r=NullVoxPopuli

template-lint: Use `octane` preset

with a few rules disabled for now until we can comply with them...

The `no-curly-component-invocation` rule should in theory be able to run without issues but it currently seems to have a small bug that is causing false positives for us (see ember-template-lint/ember-template-lint#1026)
