cosmovisor

This is a fork of CosmosSDK's Cosmovisor of this commit on branch main. It basically adds some flags to override the default folder structure, similar to #16550 with the aim to run Cosmovisor inside a docker container; see Omni's halovisor for more details.

It adds the following flags:

• COSMOVISOR_CUSTOM_ROOT: Allows overriding the default root folder DEAMON_HOME/cosmovisor containing all cosmovisor data.
• COSMOVISOR_CUSTOM_CURRENT_LINK: Allows overriding the default current link DEAMON_HOME/cosmovisor/current.

Problems it solves:

• The default cosmovisor folder structure makes it hard to run cosmovisor inside a docker container.
• The current link should be mountable, so that it is retained between container restarts.
• A single external mount with all external data simplifies the setup.
• Since root is hard coded to DEAMON_HOME/cosmovisor, it clashes with the default DEAMON_HOME/config and DEAMON_HOME/data folders.
• The current link is hard coded to DEAMON_HOME/cosmovisor/current, which is not mountable.
