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
Fixes#1935

1. Move docker build files to separate dir from docker script files
so that they won't be part of build context. Update dockerignore as well
2. Fix lib dependencies for alpine

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
using scripts.
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.
1. Align checked version with the format provided by the endpoint
2. Improve error reporting as well as install ca certificates in the docker file.

- make use of docker buildx caching when possible (helpful with local docker builds)
- introduce a reusable container workflow which is triggered by docker-release and docker-weekly workflows
- added an alpine-dev Dockerfile
- split release.sh contents into different Makefile targets
- make use of job matrix to build alpine + ubuntu in parallel
- make alpine build optional by checking for Dockerfile presence
-- as the pre-built binaries don't work with alpine, because of glibc <-> musl incompatibilities
