This pull request includes changes to the sequence number management and
testing in the `main` and `internal/seqno` packages. The most important
changes include the creation of a new `SequenceNumberManager` interface
and `SeqNumManager` struct, the addition of a function to check if a
sequence number has already been processed before enabling it, and the
addition of tests for the new function.
New sequence number management:
*
[`internal/seqno/seqno.go`](diffhunk://#diff-f671e4abbca7ae7b738bc8ef287fcbf3995062b2cc5e54ad666e3fa6f1b674dcR1-R101):
Created a new `SequenceNumberManager` interface and `SeqNumManager`
struct to manage sequence numbers. The `SeqNumManager` struct includes
functions to get and set sequence numbers, and to find a sequence number
from either the environment variable or the most recently used file
under the config folder.
Changes to `main` package:
*
[`main/cmds.go`](diffhunk://#diff-ace417b47e816a44cf3b6f6248e72453a46d9e6043f19aea9d39212e852cc373L32-R32):
a new function `enablePre` has been added. This function, acting as the
PreFunc for the enable command, verifies if the sequence number is ready
for processing by comparing it with the last executed number from the
`mrseq` file. This ensures orderly processing of sequence numbers.
*
[`main/main.go`](diffhunk://#diff-327181d0a8c5e6b164561d7910f4eeffd41442d55b2a2788fda2aa2692f17ec0L64-R68):
Replaced the `FindSeqNum` function with `seqnoManager.FindSeqNum` to
find the sequence number.
*
[`main/seqnum.go`](diffhunk://#diff-171d8d31093fac5a89b9bbe034fe628faf47dd12fad91b3205433ca95c56be52L1-L32):
Removed the `FindSeqNum` function as it has been replaced by
`seqnoManager.FindSeqNum`.
New tests:
*
[`main/cmds_test.go`](diffhunk://#diff-bdb35e68cc43b04f7c8b572233a1472169052b84e0b471c6fe578fe049784223R36-R133):
Added tests for the enablePre.

Some info is missing in the kusto logs that are present in the local
logs that makes it difficult to debug.
- Log specific command being executed at startup
(install/enable/update/etc)
- Include extension sequence number and pid at startup for debugging
from GuestAgent logs when extension logs are missing or seqNum.status
file is missing
- Log overall status file so we have better debugging when
VMExtensionProvisioning fails. This status is only sent when extension
transitions between Transitioning -> Success/Error or whenever extension
starts up.
- Update azure-extension-platform package to pull in change to increase
precision of event timestamp to include milliseconds/nanoseconds,
Previously it was RFC3339, which is in format yyyy-mm-ddThh:mm:ssZ,
which causes issue in sorting timestamps.

5. fix what seems to be a bug in fake-waagent script as it doesn't work without this fix for me
* update binaries and config to latest
* Resource governance, heartbeat and dev container changes
The main feature change here is the addition of resource governance for linux via cgroups.
We discover the current cgroup and add a sub cgroup for our purposes (limiting cpu to 1% and memory to 40MB)
I also added support for detecting a stuck vmwatch using the heartbeat file and implemented the same logic for restarts from the windows version (3 restarts per 3 hours)
As part of the development of this, I added support for devcontainer execution so we can step through the code from a dev machine into either a WSL session or a linux vm with tools installed.
I added integration tests to check process exit, OOM and cpu throttling. These changes required a few changes to the makefile and scripts.
I also updated the vmwatch binaries and added a script to download the latest ones as well
I updated the govendor files using the tool it told me to run I hope I did this right

Due to pending update of Compute-ART-LinuxExtensions go lang compiler to 1.17.x. I am migrating the code to use go modules.
https://go.dev/blog/migrating-to-go-modules
The vendor directory has been trimmed by running 'go mod init', 'go mod vendor' 'go mod tidy', no files were removed manually.
main.go has been updated to call the renamed method in github.com/Azure/azure-docker-extension/pkg/vmextension
* go mod vendor
* Ran go mod tidy and updated main.go
