set tzdata data_dir in config

[eumel8]

tzdata has a auto-update mechanism as described here If you operate asciinema in a Pod of a Kuberntes cluster with readOnlyRootFilesystem this will cause CrashLoopBackOff due the missing write permissions in the depth of the application directory. So move out this directory to /tmp/tzdata, so it can be mount by an emptyDir. At startup tzdata will fill this directory automatically:

06:43:43.238 [info] No tzdata release files found in custom data dir. Copying release file from tzdata priv dir.

Another option would be disable the tzdata update feature

Auto update of tzdata can also be disabled via Advanced Configuration of asciinema-server described here.

In the custom.exs file you can configure the tzdata module autoupdate function.
Example in custom.exs:

import Config

# Custom configuration for tzdata module
config :tzdata, :autoupdate, :disabled

I don't think having auto update enabled by default is really necessary (we don't do much if at all with timezones in this project), so I believe we should just put the line @lmarti1505 suggested in the default config.exs file. And we'll just always update the tzdata package for each new tagged release of the server. Does this sound good?

@ku1ik sounds good, thanks!

I've just released a new version with the auto-update disabled.
