 ### Compared to MooseFS ###
 MooseFS chooses to neglect small file issue. From moosefs 3.0 manual, "even a small file will occupy 64KiB plus additionally 4KiB of checksums and 1KiB for the header", because it "was initially designed for keeping large amounts (like several thousands) of very big files"
 MooseFS Master Server keeps all meta data in memory. Same issue as HDFS namenode.

 ## SEAWEEDFS - helm chart (2.x)
 ### info:
 * master/filer/volume are stateful sets with anti-affinity on the hostname,
 so your deployment will be spread/HA.
 * chart is using memsql(mysql) as the filer backend to enable HA (multiple filer instances)
 and backup/HA memsql can provide.
 * mysql user/password are created in a k8s secret (secret-seaweedfs-db.yaml) and injected to the filer
 with ENV.
 * cert config exists and can be enabled, but not been tested.
 ### current instances config (AIO):
 1 instance for each type (master/filer/volume/s3)
 instances need node labels:
 * sw-volume: true  (for volume instance, specific tag)
 * sw-backend: true (for all others, as they less resource demanding)
 you can update the replicas count for each node type in values.yaml,
 need to add more nodes with the corresponding label.
 most of the configuration are available through values.yaml

 Hi
 This PR adds support for building a snap package of seaweedfs. Snaps are cross distro Linux software packages. One snap can be installed on Ubuntu all supported LTS and non LTS releases from 14.04 onward. Additionally they can installed on Debian, Manjaro, Fedora, OpenSUSE and others. Making a snap of seaweedfs enables you to provide automatic updates on your schedule to your users via the snap store.
 If accepted, you can use snapcraft locally, a CI system such as travis or circle-ci, or our free build system (build.snapcraft.io) to create snaps and upload to the store (snapcraft.io/store). The store supports 
 To test this PR locally, I used an Ubuntu 16.04 VM, with the following steps.
 ```
 snap install snapcraft --classic
 git clone https://github.com/popey/seaweedfs
 cd seaweedfs
 git checkout add-snapcraft
 snapcraft
 ```
 The generated a .snap file from the tip of master (I could have checked out a stable release instead). It can be installed with:-
    snap install seaweedfs_0.99+git30.79371c0-dirty_amd64.snap --dangerous
 (the --dangerous is necessary because we’re installing an app which hasn’t gone through the snap store review process)
 Once installed, the (namespaced) weed command can be executed. If you accept this and land the snap in the store, we can request an ‘alias’ so users can use the ‘weed’ command rather than the namespaced ‘seaweedfs.weed’
 - Run the command
 -  Create sample config. Snaps are securely confined so their home directory is in a different place
    mkdir ~/snap/seaweedfs/current/.seaweedfs
    seaweedfs.weed scaffold > ~/snap/seaweed/current/.seaweedfs/filer.toml
 - Run a server
    seaweedfs.weed server
 - Run a benchmark
    seaweedfs.weed benchmark
 Results from my test run: https://paste.ubuntu.com/p/95Xk8zFQ7w/
 If landed, you will need to:-
 - Register an account in the snap store https://snapcraft.io/account
 - Register the ‘seaweedfs’ name in the store 
  - snapcraft login
  - snapcraft register seaweedfs
 - Upload a built snap to the store
  - snapcraft push seaweedfs_0.99+git30.79371c0-dirty_amd64.snap --release edge
 - Test installing on a clean Ubuntu 16.04 machine
  - snap install seaweedfs --edge
 The store supports multiple risk levels as “channels” with the edge channel typically used to host the latest build from git master. Stable is where stable releases are pushed. Optionally beta and candidate channels can also be used if needed.
 Once you are happy, you can push a stable release to the stable channel, update the store page, and promote the application online (we can help there).

  SeaweedFS is a simple and highly scalable distributed file system,
  to store and serve billions of files fast!
  SeaweedFS implements an object store with O(1) disk seek,
  transparent cloud integration, and an optional Filer with POSIX interface,
  supporting S3 API, Rack-Aware Erasure Coding for warm storage,
  FUSE mount, Hadoop compatible, WebDAV.
 # Grade is stable for snaps expected to land in the stable channel
 grade: stable
 # Uses the strict confinement model and uses interfaces to open up access to
 # resources on the target host
 confinement: strict
 # List of parts which comprise the snap
 parts:
  # The main part which defines how to build the application in the snap
  seaweedfs:
    # This part needs a newer version of golang, so we use a separate part
    # which defines how to get a newer golang during the build

  # An alias can be added to expose this as 'weed' if requested in the snapcraft forum
