Add flags to the run command for configuring cAdvisor housekeeping

[into-the-v0id]

PR Description

Goal of this PR is to make cAdvisor housekeeping configurable in grafana alloy (see #4685).

cAdvisor handles the configuration of its housekeeping exclusively via flags. See cAdvisor housekeeping docs and cAdvisor source code. The variable in the source code is also global - so we cannot configure this on an alloy config block level. We would need to keep this setting also global in grafana alloy. Following options:

• global options in alloy config file
• environment variables
• pass through flags

I've went with passing through the flags since most grafana alloy users already pass custom flags to alloy and it's less hassle than a new config option in the config files.

The run cli command has now the following flags:

--cadvisor.allow-dynamic-housekeeping            Whether to allow the cadvisor housekeeping interval to be dynamic (default true)
--cadvisor.housekeeping-interval duration        Interval between cadvisor container housekeepings (default 1s)
--cadvisor.max-housekeeping-interval duration    Largest interval to allow between cadvisor container housekeepings (default 1m0s)

I've also made dynamic housekeeping configurable while I'm at it (cAdvisor source code).

The defaults match the defaults of cAdvisor - so this shouldn't be a breaking change.
