Create show meta-caches sub-command within CLI

[peterbarnett03]

Purpose

We want to enable three commands for the new show command: databases, last-caches, and meta-caches. This issue focuses on meta-caches.

Requirements

With the addition of the command, the show command should add a new sub-command option for meta-caches.

Command: meta-caches
Description: View all configured meta-caches

$ influxdb3 show -h
View all active databases and configured caches

Usage: influxdb3 show [COMMAND]

Commands:
  databases     View all databases
  last-caches   View all configured last-caches
  meta-caches   View all configured meta-caches
  help          Print this message or the help of the given subcommand(s)

Meta-Caches Command

Option	Alias	Value Name	Description
--host	-H	<HOST_URL>	The host URL of the running InfluxDB 3 Core server [env: INFLUXDB3_HOST_URL=] [default: http://127.0.0.1:8181]
--database (Required)	-d	<DATABASE_NAME>	The database to view configured meta-caches
--table	-t	<TABLE_NAME>	The table to view configured meta-caches
--token		<AUTH_TOKEN>	The token for authentication with the InfluxDB 3 Core server [env: INFLUXDB3_AUTH_TOKEN=]
--help	-h		Print help information

Output

We want a tabular output. The database name should be in the top-section, plus the columns should be comma-delimited.

+---------------------------------------------------------------------+
| iox::database: <DATABASE_NAME>                                      |
+---------------------------------------------------------------------+
| name          | table      | columns        | cardinality | max_age |
+---------------+------------+----------------+-------------+---------+
| <CACHE_NAME>  | <TABLE>    | <COLUMNS>      | <N>         | <TIME>  |
| <CACHE_NAME>  | <TABLE>    | <COLUMNS>      | <N>         | <TIME>  |
| <CACHE_NAME>  | <TABLE>    | <COLUMNS>      | <N>         | <TIME>  |
+---------------+------------+----------------+-------------+---------+

Example:

+---------------------------------------------------------------------+
| iox::database: weather_data                                         |
+---------------------------------------------------------------------+
| name          | table      | columns        | cardinality | max_age |

| sensor_meta   | sensors    | type, model    | 1000        | 24h     |
| location_meta | readings   | city, region   | 500         | 48h     |
| device_meta   | devices    | make, version  | 2000        | 72h     |

[hiltontj]

There should be an (optional) --table argument to only show caches associated with the given table.

Updated requirements. Good add.
