Disable clap-provided -h flags on two subcommands

[mzabaluev]

Description

The conflicting flags were overlooked during the original clap porting in #1576, resulting in panics when query client consensus and query client connections commands are invoked.

This is an alternative to changes made in 60829af, but with no CLI breakage.

Re tests: evidently there are no integration tests to exercise these subcommands in CI. How difficult it would be to add the tests, considering that the only way to invoke these commands in a do-nothing mode is being removed by this PR?

[romac]

That's nice alternative, but if we go this way how about doing so for all commands? This way -h will never mean --help for one command and --height for another.

[mzabaluev]

@romac Unfortunately, the option also disables the long --help flags for these select subcommands.
So it's a worse solution to your renaming all height-related short flags to -H, which I assume can be an acceptable breakage for the 0.10.0 release.

[romac]

Oh I didn't realize it would suppress the --help flag as well, then yeah let's stick with -H flags and incur some breakage.

Let's close this in favor of 60829af in #1712
