chore: replace parseRawFlags with a better approach

[erezrokah]

parseRawFlags

cli/src/utils/parse-raw-flags.js

Line 13 in f9ec206

const parseRawFlags = function (raw) {

is used is several places in the codebase to manually parse flags passed to the CLI.
In some places it is redundant:

cli/src/commands/sites/delete.js

Line 40 in f9ec206

const noForce = !rawFlags.force && !rawFlags.f

cli/src/commands/addons/delete.js

Line 19 in f9ec206

if (!rawFlags.force && !rawFlags.f) {

And in other places it is used to to pass configuration to addons:

cli/src/commands/addons/create.js

Line 58 in f9ec206

const missingValues = missingConfigValues(required, rawFlags)

cli/src/commands/addons/config.js

Line 56 in f9ec206

const missingValues = missingConfigValues(required, rawFlags)

We should use the built in parsing mechanism when possible and re-visit the approach passing configuration to plugins by parsing the raw arguments ourselves.
