timescaledb_toolkit extension lost after pod restart

[JaredTan95]

as known from timescaledb docs: https://docs.timescale.com/timescaledb/latest/how-to-guides/hyperfunctions/install-toolkit/

we need to install timescaledb_toolkit on timescaledb.

Currently, helm chart will create it if not exsists during installation:

• https://github.com/tricorder-observability/helm-charts/blob/main/charts/starship/templates/database/timescaledb-extensions.yaml
• https://github.com/tricorder-observability/helm-charts/blob/09d03b15ce00f110d95418e15e5f372340edbad3/charts/starship/values.yaml#L207

but if pod restart for some reason, the timescaledb_toolkit extension might be lost.

Right now, we add an script to fast recovery it by kubectl exec the installation scripts in pod: https://github.com/tricorder-observability/starship/pull/144

We need to investigate more details about the lost reason after the pod restart.
