[OB4] Web node settings configuration page [M2]

[creativcoder]

Issue summary

• The user of an NCN can configure their own list of trusted service providers (usually will include nodes run by Bison Trails, Figment, etc. but can also be their own local node they’re running.) This can be done via the settings page for the web extension
• Support for multiple networks and switching between them (eg testnets and mainnet)
  The above two could be something like { “testnet” : { “figment” : “”, …}, “mainnet” : { “bison_trails” : “” }} and also configurable through the settings page
