1. Restrict build context in our dev/weekly builder to ease development iterations.
2. Switch weekly build to debian 12-slim because it's smaller than 24.04
3. Update our prod releases to use ubuntu 22.04

The number of keys in an _incoming_ migration indicates how many keys
were received, while for _outgoing_ it shows the total number. Combining
the two can provide the control plane with percentage.
This slightly modified the format of the response.

* feat(server): Use mimalloc in SSL calls
Until now, OpenSSL used `malloc()` directly. This PR overrides it to use
mimalloc.
Fixes#2709
* Add generate-tls-files.sh
* WIP: `cluster_mgr.py` to work with remote targets
* Documentation
* No admin port
* Support different hostname move/migrate
* Fix migrate bug
* Fix typo in --help
* fix test
* self.update_id()
Example usage:
```bash
# Create a 2-node cluster
./cluster_mgr.py --action=create --replicas_per_master=1 --num_master=2
# Move (no migration) all slots to first node
./cluster_mgr.py --action=move --target_port=7001 --slot_start=8192 --slot_end=16383
# Fill data - like run memtier
# Migrate all slots to 2nd node. One could measure how long this step takes.
./cluster_mgr.py --action=migrate --target_port=7002 --slot_start=0 --slot_end=16383
```
We had a place in tools/packaging/generate_debian_package.sh that relied on the existence of build-opt,
moreover, if it did not exist the script deadlocked.
1. Added more loggings
2. Removed the loop
3. Removed unnecessary dependency in the script on the build-dir name.

Should allow track caches where Dragonfly is not responsive to I/O
due to big CPU tasks. Also, update the local grafana dashboard.
Signed-off-by: Roman Gershman <roman@dragonflydb.io>
The dashboard used `dragonfly_up` metric to boostrap itself
but this metric does not exist anymore. I replaced it with `dragonfly_version`
In addition, the exported format changed slightly because I used the
recent grafana version to export.

Eviction Implementation
This patch provides a very simple eviction implementation for the interface mentioned above. In my opinion, the eviction algorithm approximates an LRU policy given that normal buckets always store the most recently accessed data while stash buckets are holding less active data.
The algorithm first selects a small set of segments as eviction targets. Starting from the last slot of the last stash bucket in each of the segments, we walk backward to evict key-value pairs stored in each visited slot. The eviction stopped either when a target memory release goal or the max number of evicted key-value pairs is reached. Therefore, we can upper bound the eviction time through the following two parameters that can be set when DF starts. Note that these two parameters could be retrieved and changed by user through CONFIG GET and CONFIG SET commands.

The new logrotate settings assume that dragonfly closes a log file
once it grows to large. It never rotates file that is currently open for writing.
Specifically logrotate:
1. rotate only log files
2. skip those that are currently open by as process.
3. compresses using zstd which is more cpu efficient than gzip
4. does not truncate/create old files as 0-sized blobs - just renames them

Specifiying an exact boost version is not robust.
Also we do not depend on fibers anymore and boost-context is enough.

Now this management script can:
* Create a cluster (before this PR)
* Print an existing cluster configuration
* Shutdown an existing cluster
* Move slots between cluster nodes
To support connecting to a cluster (for all new functions), I had to
change the way admin ports are defined. Instead of having the user
(optionally) specify the first port, they are hard-coded to be the
regular port + 10,000. This is done because we can't detect the admin
port based for an existing cluster (like via `CLUSTER SHARDS`).
This script allows easily setting up a local cluster.
Example invocation:
```
killall dragonfly; ./cluster_mgr.py --num_masters=3 --with_replicas

Currently deployed packages have version in the filename which makes it much harder to fetch

This change fixes the filename and also removes some redundant code.

Alpine images don't have bash installed by default, so we need to use
`/bin/sh` instead. This follows the *same existing convention that
we follow in the `entrypoint.sh` script*.
Both ubuntu and alpine images have been tested (i.e healthchecks to
pass) to work with this change.
