unify configuration formats

[runborg]

the format used for configuration files are by now quite different.

• Main configuration will use a toml file,
• polldevs uses <key>:<value> with a new element/object on every name key
• secrets uses <username> <password>

What about unifying all these formats to use the same toml structure?
example polldevs format:

[defaults]
interval = 5
community = "<community>"
domain = "<domain-name>"
statistics = true
hcounters = true


[router.<router-name>]
address = "<mgmt-ip>"
interval = 2
priority = 500
ignorepat =  "Mgmt"
timeout = 11

example secrets:

[users]
username = "<password>"

or

[user.<username>]
realname = "Users Real Name"
password= " <password>"
....

this later then supports multiple attributes pr. user if this is needed.

We could also do arrays:

[[router]]
name = <router-name-1>
address = "<mgmt-ip-1>"
interval = 2
priority = 500
ignorepat =  "Mgmt"
timeout = 11

[[router]]
name = <router-name-2>
address = "<mgmt-ip-2>"
interval = 2
priority = 500
ignorepat =  "Mgmt"
timeout = 11

and

[[user]]
username = "<username-1>"
password= " <password-1>"
magic = false

[[user]]
username = "<username-2>"
password= " <password-2>"
magic = true
favorite-date = 1970-01-01T00:00:00Z

We could also do arrays:

as we never should have two routers or users with the same name i see no reason to use arrays. i think its better to user the username/routername as a key identifier on this

i also se the use for creating eg. read-only users.. with no permissions to change/update things.. so a format witch allows multiple options pr. user is a good thing :)
