Tom DNetto 767e839db5 all: implement lock revoke-keys command
The revoke-keys command allows nodes with tailnet lock keys
to collaborate to erase the use of a compromised key, and remove trust
in it.

various: add golangci-lint, fix issues (#7905)

golang-ci, fixes the issues reported, and adds a GitHub Action to check

Will Norris 71029cea2d all: update copyright and license headers
This updates all source files to use a new standard header for copyright
and license declaration.  Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.

This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

Updates #6865

Adrian Dewhurst 8c09ae9032 tka, types/key: add NLPublic.KeyID
This allows direct use of NLPublic with tka.Authority.KeyTrusted() and
similar without using tricks like converting the return value of Verifier.

Tom DNetto 79905a1162 tka: make storage a parameter rather than an Authority struct member
Updates #5435

Based on the discussion in #5435, we can better support transactional data models
by making the underlying storage layer a parameter (which can be specialized for
the request) rather than a long-lived member of Authority.

Now that Authority is just an instantaneous snapshot of state, we can do things
like provide idempotent methods and make it cloneable, too.

Tom DNetto f580f4484f tka: move disablement logic out-of-band from AUMs
It doesn't make a ton of sense for disablement to be communicated as an AUM, because
any failure in the AUM or chain mechanism will mean disablement wont function.

Instead, tracking of the disablement secrets remains inside the state machine, but
actual disablement and communication of the disablement secret is done by the caller.

Tom DNetto f50043f6cb tka,types/key: remove dependency for tailcfg & types/ packages on tka
Following the pattern elsewhere, we create a new tka-specific types package for the types
that need to couple between the serialized structure types, and tka.
