* Emit new `AgentMetadataEvent`
Part of https://github.com/gravitational/cloud/issues/3550.
This commits adds a new `UpstreamInventoryAgentMetadata` that is sent
from a Teleport agent to an auth server.
Once received, it is transformed into an `AgentMetadataEvent` and sent
to PreHog.
Most `UpstreamInventoryAgentMetadata` fields are intentionally kept as
empty in this PR. Follow up PRs will be opened with the mechanisms
required to fill them (as described in #21337).

* Add missing import
* Handle error
* Revert "Spawn gorountine that fetches metadata on each new stream"
This reverts commit fe4f2790be.
* Send agent metadata to auth server once per stream
* Improve note about agentMetadataDone
* Don't process command output & file content on the agent
Since agents cannot be trusted, regex validation and sanitization should
happen in PreHog anyways. So this commit removes such logic in favor of
moving it to PreHog.
* Fix lint
* Trim space
* Move handling of `AgentMetadataEvent` to `handleControlStream`
* Use cached hello message

* Remove unused import
* Add parsing of command output / file content back
* Usage reporter refactor
* Usage reporter refactor
* Add missing handling of inventory agent metadata msg
* Fix ICS usage reporter
* Improve comments
* Add cached `metadata.Get*` methods
* Use systemctl status instead of is-active
* Add `Metadata` struct
* return pointer in `FetchMetadata`
* Pass context to `GetMetadata`
