Add seqcli setting names|show|set|clear commands

[nblumhardt]

Seq.Api needs an update to make all settings available (we'll do that in the near future :-)) but the primary utility of this command group right now is the rotation of Azure AD and OIDC client secrets, which can be set using:

echo "some secret" | seqcli setting set -n AzureADClientKey --value-stdin

and similarly for OpenIdConnectClientSecret.
