This turns the output from: ``` ❯ vtctlclient -server "localhost:15999" ListAllTablets -h Usage: ListAllTablets <cell name1>, <cell name2>, ... Lists all tablets in an awk-friendly way. ListAllTablets Error: rpc error: code = Unknown desc = flag: help requested E0528 19:52:46.564223 77260 main.go:76] remote error: rpc error: code = Unknown desc = flag: help requested ❯ echo $? 1 ``` into: ``` ❯ vtctlclient -server "localhost:15999" ListAllTablets -h Usage: ListAllTablets <cell name1>, <cell name2>, ... Lists all tablets in an awk-friendly way. ❯ echo $? 0 ``` Signed-off-by: Andrew Mason <amason@slack-corp.com>
This is admittedly pretty hacky, and I had to spend a lot of time messing around with cobra to make this behavior correctly. But, it works! Signed-off-by: Andrew Mason <amason@slack-corp.com>
Also remove the custom help func hack, because it turns out we don't actually need it (thank goodness) Signed-off-by: Andrew Mason <amason@slack-corp.com>

Description
This PR adds a shim to the new vtctldclient to allow running legacy vtctl commands that have not yet been migrated. The intention here is to allow users to start updating any scripts they have now (going from
vtctlclient [args ...]tovtctldclient LegacyVtctlCommand -- [args ...]), and then dropping the old client should be ideally a no-op, or at least far less painful.Examples!
client-side help
server-side help showing available commands
Getting tablets, both ways
Getting per-command server-side help, using legacy commands that take flags, etc
