Add multi special character password handling to collect

Add handling for passwords that have duplicate special
characters.

For instance without this update, passing collect the following
sudo password would fail while with this update it succeeds.

    [[Pa$$word123]]

The following characters are verified to require escapes.

1.  [ and ] (square brackets)  [$$Copper1$$]   … escaped by collect
2.  ? (question mark)          ?Copper123?     … escaped by collect
3.  $ (dollar sign)            $Copper123$     … escaped by collect
4.  " (double quotes)          “<Mooser123>”   … escaped by collect
5.  \ (backslash)              \Mooser1\       … escaped by collect

Note that the backslash '\' must be escaped by the user. For instance to enter a password with backslashes that reads like this \Copper123\ it must be escaped going in like this \\Copper123\\

The following special characters are verified to not require escapes.

6.  & (ampersand)              &Copper123&     … no escape needed
7.  ( and ) (parentheses)      (Duffy123)      … no escape needed
8.  { and } (curly braces)     {HealthCare123} … no escape needed
9.  ; (semicolon)              ;Copper123;     … no escape needed
10. | (pipe)                   |PasswdTst123|  … no escape needed
11. < (less than)              <Mooser123>     … no escape needed
12. > (greater than)           <|>Copper123<|> … no escape needed
13. >> (double greater than)   >>Mooser321<<   … no escape needed
14. ' (single quotes)          ‘Copper911’     … no escape needed
15. * (asterisk)               *Mooser123*     … no escape needed
16. # (hash or pound sign)     #Mooser123#     … no escape needed
17. ! (exclamation mark)       !!@$Mooser1$@!! … no escape needed
18. ~ (tilde)                  ~Copper1~       … no escape needed
19. @ (at symbol)              @Passwd1@       … no escape needed
20. ^ (caret)                  @^Myword1^@     … no escape needed

Test Plan:

PASS: Build and Install Debian Image
PASS: Run collect with typical password

The following password patterns were verified to be parsed
properly and all verified to work with collect.

PASS: [[Pa$$word123]] -> \[\[Pa\$\$word123\]\]
PASS: $$Passwd123$$ -> \$\$Passwd123\$\$
PASS: \Passwd1\ -> \\Passwd1\\
PASS: "Passwd1" -> \"Passwd1\"
PASS: [Passwd1] -> \[Passwd1\]
PASS: $Passwd1$ -> \$Passwd1\$
PASS: Li69nux* -> Li69nux*
PASS: "[Li69nux*]" -> \"\[Li69nux*\]\"
PASS: St8rlingX* -> St8rlingX*
PASS: $t8rlingX* -> \$t8rlingX*
PASS: $[$$Passwd1$$]$ -> \$\[\$\$Passwd1\$\$\]\$
PASS: "]\\$Passwd1$\\[" -> \"\]\\\\\$Passwd1\$\\\\\[\"
PASS: [[$$$[Passwd1]$$$] -> \[\[\$\$\$\[Passwd1\]\$\$\$\]
PASS: ""[[[$$$Passwd1$$$]]]"" -> \"\"\[\[\[\$\$\$Passwd1\$\$\$\]\]\]\"\"
