Support adding specific bucket(s)

Background

• Now only extras and nonportable can be installed by this action, but the other bucket can't be installed

  Acceptance criteria

• Support to freely specify bucket to install
  • With injection attack prevention (may check bucket name capable characters)
• Support existing add_extras_bucket and add_nonportable_bucket flags for transition from current usage

[MinoruSekine]

For prevention of injection attacks, it will be useful to validate string to specify bucket(s) with codes like following.

if('extras nonportable' -inotmatch '^(\w+\s*)+$') {Write-Error 'Illegal bucket(s) name.' -ErrorAction Stop}

Now I've decided only known buckets will be supported in this issue 😃
